Introduction

• For our project, we have chosen to design a hydraulic log splitter that is capable of being towed by a vehicle by using engineering methods that we have obtained throughout the years.

What we are trying to accomplish

Overview of Project

• The Project is divided into three main parts:– The Trailer Design– The Hydraulics and Pump Design– The Control System

Introduction

• After we all have done our design work and have chosen all of the necessary parts that we will need for the project, we will all work on the project together at one of our homes.

• We will have all of the necessary tools and equipment needed to construct the log splitter such as welding machines, tools, etc.

Trailer Design

• Jordan Millet• Goal: To design a trailer that will be able to

support a certain amount of weight and capable of traveling at a maximum speed of 45 miles per hour.

Trailer Design

-Objective: To design the trailer in a way that you flip the trailer the horizontal position that you tow the machine in, to a vertical position that is needed for use.

Trailer Design

• Trailer will be made with W-beam (w150-22)• HSS (High Speed Steel) aluminum for the

tongue of the trailer.• Estimated Weight: 400 pounds

Trailer Design

When the trailer is in the vertical position the height will be 5 feet.

• 4 feet from tire to tire• We will use two 16 inch tires (Max Speed of 45

mph)• 2” hitch to hook up to a truck

Hydraulic System

• Ridge Bourgeois• We will design a hydraulic system that is able

to support a design force.• This force is the force needed to split a log

with maximum of two foot in length.

Hydraulic System

• We will have to find suitable valve systems for the hydraulics and select the capacity of the hydraulic pump.

Hydraulic System

• Other things that we will have to take into account:– Types of lubricants to use– What size of cylinders for the hydraulics?– What size motor needed for the hydraulics?– What size of reservoir to store hydraulic oil?

Hydraulic Design

• Engineering designs and practices that will be used such as mechanical design, and fluid mechanics.

• We will have a drawing of the system on Auto Cad.

Control System

• The control system is the main part to make the wedge go up and down in order to split logs.

• The control system determines the amount of hydraulic pressure that will be exerted to the cylinder.

Control System

• Detent Control System is the type of Control system that we have decided to use.

• Two-Way control system.• Auto-Return• Safety!!!

Control System

• The detent control system will be located directly on top of the hydraulic cylinder.

• The detent control system will be anchored to the cylinder using bolts and a cover connecter.

Parts of the Control Valve

• Port A• Port B• Inlet Port• Outlet Port• Pressure Release Valve

Parts needed for Log Splitter

• 2-inch Ball Coupler• Hydraulic Cylinder• Mounting Plates• Wedge• Splitting Beam• Engine (Donated)• 2 16 inch Tires• Hydraulic Fluid Filter• Hydraulic Pump

Parts for Log Splitter

• Beam Bracket• Support Leg• 1 ¼” Safety Chain around 12 inches long• Tongue made of HSS 3/16 x 2 x 2• 1 axle• 2 spindles and 2 hub caps• One W beam ¼ x 6 x 6 (W 150-22) 60”• Hydraulic Hose• Hydraulic Hose

Potential Challenges

• There will be some challenges associated with the project.

• Cost of parts• Another challenge will be to find people who

may be willing to donate some parts to us.• Time Management

Questions/ Calculations

– We will have a 5.5 HP (196 cc) motor– 4 x 22” cylinder– Max hydraulic pressure is 3500 psi– Single axle trailer with 2 16 inch wheels– What size pump?– What size oil reservoir? 5 gallon reservoir filled

with 10Aw32

Question/Calculations

– What type hydraulic hoses? A flexible, rubber hydraulic hose that can handle pressure over 3500 psi.

– What types of controls? Two way detent control system that has auto return

– Which type of material to use for the trailer? W-beam (W150-22) and HSS aluminum

Questions/ Calculations

– How will the components mount on the trailer frame? Welding, nuts, bolts, mounting brackets

– How much would it weigh? Roughly 400-450 pounds

Timeline

• By the end of October/Early November– Research possible types of structures/shapes of possible materials

to use (Trailer Design)– Have a rough sketch of the structural shape of the trailer drawn out

(Trailer Design).– Research hydraulic systems and possible hydraulic designs

(Hydraulic Design).– Find out what type of lubricants to use (Hydraulic Design).– Find out which type of hydraulic system to use (Hydraulic Design).– Research control systems and when they are used (Control Design).– Find out what type of control system to run the hydraulics (Control

System).

Timeline

• By the end of November:– Pick which type of material to use for the trailer (Trailer

Design).– Have a drawing of trailer design on Auto-Cad (Trailer Design).– Find out what size oil reservoir and what size cylinder to use

(Hydraulics Design).– Find out what HP motor and what size oil pump (Hydraulics

Design).– Pick control system needed for project (Control Design).– Draw a schematic of wiring and circuit of the control system

(Control Design).– Work on final presentation (All).

Timeline

• December-End of semester– Make necessary changes/ modifications to design

for final presentation.– Continue working on presentation and prepare a

power point on the project progress.– Final presentation

Moving Forward:

• Begin construction of the log splitter starting with the frame.Will get most of parts needed during the Christmas break

• Have a fully functional hydraulic log splitter by the end of next semester.

• Make modifications as needed
