FEATURESMOTIONHydraulics is the technology of choice for moving or lifting heavy loadsor exerting precisely controlled forces. But one of the fastest-growingareas for hydraulics is in materials and structural test equipment.With proper controls, hydraulic actuators can apply and hold exact-ing forces on an object. And they can generate varying load cycles that simulate a lifetime of real-world stresses and wear in an accelerated time span. Aerospace and automotive-equipment manufacturers are among the early adopters who are reaping the benefits.PCs versus motioncontrollersPersonal computers, with their ability to collect, display, and archiveinformation, have become the de facto standard computing platformsfor testing and data acquisition. Besides the fact that PC hardware pro-vides the highest level of computing performance per dollar invested, a wide range of readily available software has made it relatively quick and WHATS THIS?When you see a code like this, takea photo of it with your smart phone(iPhone 3G-S gives best results) and,using software fromwww.neoreader.com, you will be connected to relevant content on machinedesign.comCombining hydraulics and a PC with the right motion controller ensures testing applications measure up.The Innkeeper tester exertsmultidirectional forces onanautomotive wheel while it spinsinside a rotatingdrum.

They could also earn points for getting their ro-bots to elevate themselves above the playing surface at theend of the game.Even for engineers who understand all the mechani-cal, electrical, and control concepts involved, building a robot fromscratch in six weeks could be a tall order. Do-ing it with a teamof high schoolers creates a real pressurecooker, says Alan Ostrow, who heads Miss Daisy, the teamat Wissahickon High School, Ambler, Pa., that won theChairmans Award, FIRSTs highest honor, in April.Some teams rely on adult engineers to design their ro-bines the excitement of varsity sports with technology.Students competing in FIRST events can win awardsfor design, teamspirit, professionalismand maturity, and overcoming obstacles as well as for scoring the most pointsin competitions.

Theres a newly developed game each year, but a carpeted field roughly thesize of a basketball court and em-phasis on cooperation among teams, creativity, professional courtesy, andsafety are usually the norm.Robot-design challenges go farbeyond creating a vehicle that movesin response to radio control. Theserobots are equipped with sensorsand other components professionalengineers would recognize, includ-ing machine vision that must be pro-grammed to recognize targets, ac-celerometers, gyroscopes, opticaland magnetic encoders, and electric motors that need to be matched to gearboxes.Robots must be able to operateautonomously for one segment of thegame, and then switch to semiauto-nomous radio control. In addition, because organizers randomly assign three-teamalliances that compete to-gether, teams need to choose whethertheir robot should specialize in onepoint-scoring task or be multiskilled.Alliances change from match to match in the initial competition stages, but top teams choose others to join their alliance going into the play-off rounds. A team with a specialist robot might look to join with teams whose robots round out its skill set.In this years competition (seeBreakaway bots), teams scored points by having robots send ballsThats exactly the vision Dean Kamen, inventor, entrepreneur, and founder ofFIRST, Manchester, N.H., had for the FIRST Robotics Competition when it started 19 years ago.This years championship in Atlanta, April 15 to 17, was the culmination of a three-month season for more than 45,000 students from12 countries. Startingin January, student teams designed and built robots that would compete both with and against other teams robots for top honors.Kamen founded FIRST, which stands for For Inspiration and Recognition of Science and Technology in 1989 to motivate young people to pursue educa-tion and career opportunities in science, technology, engineering, and math, and build self-confidence, knowledge, and life skills.

In April, for example, the number of mass layoffs companies cutting at least 50 people numbered 1,856 as employers shed over 200,000 jobs, according to the Dept. of Labor. Almost 450 of these employers were manufacturing companies.It looks as though mass layoffs will be a fact of life for some time to come. So it is fair to ask whether companies that adopt this strategy are being short-sighted or pragmatic. Wayne Cascio, a professor at the University of Colorado, Denver, has researched this point for much of the last two decades. Working with colleagues, he looked at companies that were part of the Standard & Poors 500 from 1982 to 2003, sorting them into categories each year based on whether or not they cut employees and shed assets.He then looked at what happened one year before a downsizing until two years after to see whether company financial performance was better or worse than competitors in the same industry. The results were noteworthy. Companies that purely downsized cutting employees and nothing else never outper-formed their competitors. The only companies that did well financially were those that grew their businesses by adding both assets and employees.We were looking at downsizing from the standpoint of a management decision. If you are a manager, you want to know the best strategies for profit-ability over time, says Cascio. We found that investors who bet on downsizers wouldnt have done well.Cascio has also looked at companies that have restructured or reorganized themselves to see if there are similar trends. We found companies sorted them-selves into two camps. One had the management philosophy of running the place with the least number of people possible. Another smaller camp adopted a different approach by figuring out ways of better using the people they had.The classic example of a company in the latter camp is Lincoln Electric Co. which, in the early 1980s, came up with the Leopard program to avoid laying off employees during a downturn. In it, factory and clerical workers volunteered to be trained as assistant salespeople. One of the opportunities they identified was a market for home-welding equipment through big-box retailers, says Cascio. Lincoln had never thought about that area before. It turned into an $800 mil-lion a year business that didnt exist until Leopard teams went out and found it.And though big layoffs make headlines, Cascio claims an increasing number of firms are taking a different approach. Right after 9-11, we looked at Fortune Magazines list of the best 100 employers to work for. About 80% of those com-panies had no layoffs the previous year. That was also true for 2008 and 2009, he says. Companies know that people have long memories and that when the recession is over, they will need to hire again. So a lot of firms now use layoffs as a last resort rather than as a signal to the market that they run a tight ship.

Hence we have so-cial programs that hurt everyone.I earned one of these bogus rewards. I deserved and earned a certain level of membership in a company club honoring produc-tion. During December, the last month of the annual program, management began handing out bonus points to people who did not deserve them. This was an at-tempt to boost the number of win-ners at the base level. The extra Too much positive feedbackI cannot begin to tell you how much I agree with your editorial (Positive reinforcement run amok, April 22).You could not be more correct when you say that too many acco-lades lead to mediocrity. And this attitude to reward everyone for everything doesnt only affect chil-dren but our society as a whole.The recipients of these false accolades begin to expect them even when not deserved. Then, when they dont get a reward, their efforts greatly decrease and pick up just marginally when the next reward event rolls around.Our society has become lacka-daisical because of attitudes like this. People who only perform mar-ginally begin to expect to be re-warded even though not deserved. This activity depletes the real re-wards that should go to outstand-bonus points pushed me into the second level of membership and I got invited to a company banquet. I did not think anything about it until I read your commentary and now I have mixed feelings about it because, yes I deserved basic membership but did I really earn advanced membership???David EngmanIts ironic that Leland Teschlers editorial about positive reinforce-Control theory trumps political correctness As any control engineer will explain, a system that relies only on positive feedback will be unstable.

I still have a daugh-ter in school and I see this type of thing backfiring all the time. I really think it begins to set them up for bad experiences as adults. Because in the real world, nobodys looking for reasons to praise you. (Unless to soften you up before telling you there will be no raises this year.) They only seem to care enough to talk to you when youve done something wrong.Terry PersunLee, your everybody gets a tro-phy editorial is right on. Kids know whats happening, and theyre not buying it. I remember my 4-year-old girl bringing home a trophy from school and asking Daddy, why ment appeared in the same issue with the salary survey. Let me con-nect the dots. Variations among engineering salaries are minimal, regardless of which variable you consider. We all get rewarded about the same $70 to 100K, a range that is even smaller after taxes. An engineer whose innova-tion adds millions to a companys bottom line probably might get a 3% increase rather than 1%. The idea of compensation being re-lated to performance is manage-ment fiction in most companies. The reality is that compensation is fundamentally a matter of sup-ply and demand, as evidenced by low or no wage increases even in companies having excellent profits in these days of high unemploy-ment. Of course, outsourcing and the H1B visa program have con-tributed to the overly large supply of technical talent and both keep compensation artificially low for RS=112JNE24,2010 MAOHlNE Design.com 14Dedicated to the Science of MotionAoto|oc|, loc., 101 2o|o Lt|vo, l|||sbutq|, lA 15228l|. =12927=70 lo. =12927=59 Lo||. so|osooto|oc|.cowww. oero| ecb. comAl1009C/ o c | o c | \ c | o . o o|. | oo .| o| os Co o, |. | oo |. coc ' oco C|. onsemb|e"pog:Verso|||e, S|x Ax|s, S|ond-A|one Mo||on Con|ro||erLosob|oLpoq |s Aoto|oc|'s oo|qoooto||oo s|oodo|ooo o||oocoo|to||ot.

My first employer had no PEs working for them. My sec-ond employer had two PEs, in a different department, in a dif-ferent facility; so my experience worki ng there di d not qual i fy me to take the PE exam. My cur-rent employer does have two PEs working for them, and I intend to take the PE exam once Ive been here for 5 years. Its easy to see the value of a pro-fessional certification based on skill and capability. Its reasonable to require some work history before the professional certification of engineers. However, its ridiculous to base qualifications for a profes-sional certification on a must be invited by a member Rotary Club-style restriction.Russ D. Bafford III believe that this would be an efficient method of transferring the power to the ground.Ken StewartLast of the PEs versus non-PEsI n a recent letter to the editor (April 22), Mr. Bernell Shoff, PE, challenged non-PEs claiming to be just as intelligent as PE holders to basically pony up and take a day and go for the exam and get licensed. So as soon as Mr. Shoff, PE, can tell me how to get around the good old boy network which excludes capable engineers from qualifying to take the exam, Ill go take a day, school a test, and proudly display a PE behind my name.Id love to take the PE exam. Id destroy it just like I did the EIT exam 12 years ago as a senior in an accredited BSME program. Un-draulics offer power density un-matched by any other technol-ogy... I think this is basically a faulty conclusion, and will lead to faulty constructions.Albert A. CrookstonI believe that the main advantage for hydraulics in wind turbines is that most of the equipment is on the ground. The main disad-vantage is the inefficiency of the hydraulics.Here is a possible mechanical solution. Only main drive machin-ery is in nacelle. Put two low-speed double-bevel gear cases with a fixed horizontal crankshaft with four throws at 90 up in the nacelle. At ground level, mount a duplicate shaft with four throws connected to the drive gear case/generator. Between the two cranks (in the tower) place four pretensioned steel cables with ball-bearing rod ends at each end.RS=114[ MOTOR TRUTH #2 ]Can I really save money by installing a smaller motor?The truth? You just might be able to. If you look at your entire drivetrain, youll probably fnd that if you replace inefcient components (which can waste up to 50% of the energy they use), youll be able to install a new, smaller, high-efciency DR motor and still get the power output you need. And, youll save energy at the same time, because your current oversized motors may be wasting energy to overcome the inefciencies of your entire drivetrain.SEWs new DR motor series is specifcally designed to work with a total system, including our helical bevel gearboxes and electronic drives, to provide you with maximum energy savings.

MrazThrough-hole reflow beefs up circuit-board connectionsThrough-hole reflow (THR) is a recently developed method of attaching components to printed-circuit boards built with solder-reflow processing. In fact, THR and surface-mount devices (SMD) can be handled at the same time and on the same equipment. This could make wave soldering obsolete and save manufactur-ers up to 40% on the cost of connecting components to circuit boards.One company pioneering this new process is Wieland Electric GmbH, a German firm with U.S. headquarters in Burgaw, N.C. (www.wieland.com). They say THR makes strong connections to PC boards, letting electrical components better withstand mechanical loads. THR has been shown to create bonds much stronger than those made using surface-mount technology (SMT). This means THR components, particularly terminal blocks and connectors, can withstand the mechanical forces required during termination and header-and-plug-mating processes. Components can be delivered in trays or tape and reel, so they are suitable for pick-and-place automation as well.Wieland Electric offers THR connectors in 3.5, 3.81, 5.0, and 5.08-mm pitches for both two-piece connectors and one-piece terminal blocks.

(www.balseal.com), consists of a graphite-reinforced PTFE seal-ing ring energized with a canted-coil spring coupled with a high-tem-perature, thermoplastic antiextrusion element and a metal locking ring. The hardware holds the seal in place and prevents material from extruding, despite little or no clearance between the seal and rotat-ing shaft. The components work together to ensure seal wear is at the lip-contact area, not the hinge point. This gives the seal long life and improves sealing.

For the truly eco-conscious drivers, an optional full-length solar roof generates electricity to keep the car interior cool when the car is parked. And if the panel is used to recharge the batteries, it can add two to three miles per day, if the sun shines.

This The Karma, a four-door hybrid sports car from Fisker Auto-motive, Irvine, Calif., has been rescheduled to go on sale next Visible in this view of the carrier system are some of the motors and adjusters in place at the Rock-Tenn papermill. Each motor employs a Fraba DeviceNet encoder for feedback.30 encoders later, carrier belts stay on trackOptical encoders working over a DeviceNet network let a paperboard mill automate the positioning and tensioning of conveyor belts.At the Aurora, Ill. mill operated by Rock-Tenn Co., each of 10, 170-in.-wide wire mesh carrier belts ferry binder board through a 240F dryer. The belts tend to wander toward the side of the conveyor frame and rub against the frame if they are not periodically recentered. To automate the positioning and tensioning of the belts, Chicago Electric, Carol Stream, Ill., put a Fraba Inc. (Hamilton, N.J.) Optocode (OCD) DeviceNet encoder and a half-horsepower Marathonac motor on each of the 30 axes. The installation was economical partly because one DeviceNet card handled all of the high-resolution, absolute encoders. Control was via Control Techniques (Eden Prairie, Minn.) half-horsepower ac vector drives run from an Allen-BradleyControl/Logix PLC and a touchscreen.Using DeviceNet encoders and relatively inexpensive drives, motors, and a PLC kept Chicago Electrics quote at just under $200,000. A more-typical system with servo or stepper technology and separate interface cards for each of the 30 encoders would have cost as much as 50% more. Each OCD absolute encoder uses an integrated Opto-ASIC that provides up to 30-bit multiturn resolution and can withstand the heat near the dryer. At Aurora, the fully automated closed-loop system for positioning the belts replaced a completely manual process. If a belt slackens, a worker taps a button on the touch screen to take up the slack.

But the company has included positive reinforcements, too, like an in-dash driver informa-tion center that updates your gas mileage in real time.Small efficiency gains also come from electronic power steer-ing (the engine no longer has to run hydraulic boosters) and low-rolling-resistance tires. Although these are well-accepted strategies for boosting fuel economy, they both contributed to the trouble I had driving the Equinox uphill in wet snow. The wheels slipped and could not track straight. At the same time, the power steering didnt provide enough tactile feed-back, so the steering wheel felt dis-connected from where the vehicle was actually headed.However, once you accept that GM has stuffed a small sedans engine under the hood and that you may need better tires, there is plenty to like about the Equinox. Engineers at GM werent totally fo-cused on fuel economy; they took a good look at comfort, too.The cushy driver and front pas-senger seats were cherry-picked from the Cadillac CTS. A full 8 in. of travel, plus height and lumbar adjustments, accommodate just about any size driver. Rear seats are almost as comfortable, split 60/40, Some of the criticisms lev-eled against General Motors have been that it wasnt focused on making the high-efficiency cars Americans wanted to buy and that it was falling behind in green tech-nology. The 2010 Chevrolet Equi-nox is GMs answer to its detractors.The Equinox is redesigned for 2010 with a focus on boosting fuel economy. So the front-wheel-drive model comes with a 2.4-liter four-cylinder, direct-injection engine the EPA estimates burns 22 mpg in the city and 32 mpg on the high-way. Adding part-time all-wheel drive drops the estimates to 20 and 29 mpg, respectively. Drivers can also opt for a V6 in LT and better trims.The four-cylinders highway fuel economy beats that of Equinoxs competitors, including the Honda CR-V and Ford Escape, by four or five points. It also beats the Escape Hybrid by one point, although the hybrid does far better in town than competing models.But an empty Equinox still weighs 3,761 to 3,838 lb, depend-ing on options, so barring anti-gravity technology, how did they do it?Most of the efficiency comes from the smaller engine and six-speed automatic transmission. The transmission defaults to eco mode, which forces it to upshift earlier and downshift later. The driver can bypass this mode to get more low-end power.That strategy works for most driving situations, like highway cruising or tooling around town. But try to floor it on an on-ramp to get ahead of a semi, and the Equinox is all bark and no bite.

The track winds through a tunnel in the concrete-block shielding and stops at the focal point of a neutron beam. Here, isotope samples mounted on the locomo-tive absorb bombarding neutrons and give off gamma rays. Samples differ in the number of neutrons present in their nuclei, and UM re-searchers are measuring gamma-ray intensities to chart energy levels of nuclei in each sample. The beam, fatal to man, makes the engine only slightly radioactive.
