DESCRIPTION AND
CHARACTERISTICS
The APS 113 ELECTRO-SEIS has been
optimized for driving structures at their
natural resonance frequencies. It is an
electrodynamic force generator, the
output of which is directly proportional
to the instantaneous value of the
current applied to it, independent of
frequency and load response. It candeliver random or transient as well as
sinusoidal waveforms of force to the
load. The armature has been designed
for minimum mass loading of the drive
point. The ample armature stroke allows
driving antinodes of large structures at
low frequencies and permits rated force
at low frequencies when operating in a
free body mode.
The unit employs permanent magnets
and is configured such that the armature
coil remains in a uniform magnetic field
over the entire stroke range - assuring
force linearity. The enclosed, self-cooled
construction provides safety and
minimum maintenance. Attachment
of the armature to the drive point is
accomplished by a simple thrust rod
provided by the user.
A low frequency amplifier, such as the
APS 114 or APS 124 DUAL-MODETM
Power Amplifier, is required to provide
armature drive power.
MODES OF OPERATION
Free Armature Mode In this mode, the
armature provides the reaction mass for
force delivered to the test structure via
the shaker body. Auxiliary reaction mass
may be added to the armature to
decrease the low frequency limit for rated
APS 113 with 0052 Auxilliary Table
force operation. The APS 113 and 0112
Reaction Mass may be used in a verticalor horizontal free armature mode with
rated force down to 2 Hz. Feet and
carrying handles are provided for ease
in placement of the shaker on horizontal
test surfaces.
Fixed Body Mode By providing a
rigid attachment between the body
and ground, the full relative velocity and
stroke capability is available for load
motion. Maximum rated force can be
delivered down to 0.01 Hz and 70%
maximum to 0 Hz.
APS 113 with 0112 Reaction Mass
Free Body Mode In this mode, the
body provides the reaction mass. Load
and body motion are accommodated
within the total relative velocity and
stroke. Because of the high cross-axis
stiffness provided by the armature linear
guidance system, the shaker may be
supported above ground level by means
of suspension lines attached to the body -or the shaker may be supported from
beneath by the APS 0072 Cradle
Assembly which supports the armature
directly and the body via the guidance
system. This provides a convenient
mounting for introducing force parallel
to a horizontal mounting surface.
Examples of such surfaces include floors,
roofs, platforms, cabinets, bridges and
tanks.
Shaker Table Mode Auxiliary tables
are available which attach directly to

APS 113-AB-ES Extended Stroke
the armature and enable the basic
shaker to provide long stroke, low
frequency excitation to components or
model structures mounted on the tables.
APS 0052 Auxiliary Table provides a
10 in x 10 in horizontal load mounting
surface for horizontal motion rated for
50 lb test loads. The APS 0077 Auxiliary
Table provides the same load mounting
surface for vertical motion. The APS
0078 provides for both vertical andhorizontal applications.
OPTIONAL CONFIGURATIONS
APS 113-AB Air Bearing Model
Air lubricated bushings replace the
linear ball bushings used in the basic
ELECTRO-SEIS armature guidance
system. In addition an air distribution
system, tie down and leveling base
are provided.
The near zero friction of the air bushings
is an essential feature for measuring
resonance decay rates in very lightly
damped structures.
The Air Bearing configuration extends
the application of the basic APS 113 to
include the calibration and evaluationof accelerometers and other motion
transducers in the seismic frequency
range.
APS 113-LA Lightweight Armature and
APS 113-AB-LA Air Bearing-Lightweight
The body of the ELECTRO-SEIS Shaker
is retained but the armature and guidance
system are replaced with elements offering
substantial weight reduction. The drive
coil is lightened - with corresponding
reduction in maximum force - and the
armature guidance system elements are
reduced in size and weight. This results
in a corresponding reduction in cross axis
stiffness and load carrying ability. The
long stroke capability is retained and the
frequency range for maximum force output
is extended to 100 Hz.
APS 113-AB-ES Air Bearing - Extended
Stroke Used for Modal Excitation of
structures where a longer stroke is
required.
APS 113 Air Bearing Shaker
The Lightweight Armature is a desirable
feature when using the shaker for
exciting structures having low modal
mass.
APS 113 LZ Low Impedance Coil
All features of the basic ELECTRO-SEIS
Shaker are retained. The drive coil is
wound in a manner which allow series
or parallel connection, offering the user
the choice of standard or low impedance.
This option is required if the shaker is to
be used with the APS 124 DUAL-MODE
Power Amplifier for extended frequency
range or random noise excitation.
APS 113-HF High Force Coil All
features of the basic ELECTRO-SEIS
Shaker are retained as in the APS
113-LZ. The drive coil is provided
to match the APS 124 DUAL-MODE
Power Amplifier for 40% increase in
force with a 50% duty cycle (1/2 hr
cycle).

PERFORMANCE
One application of the APS 113 ELECTRO-SEIS is to
determine the dynamic characteristics of mechanical
structures. At resonance, a large amount of energy is
contained in the structure, and the shaker must accommodate
the resulting motion. However, it need only supply the real
mechanical power dissipated by damping mechanisms within
the structure.
If a drive point on a structure in resonance is vibrating
with a velocity of 30 in/s and a force of 30 lb is required to
sustain the vibration level, then the shaker will be delivering
approximately 50 watts to the structure. Such a load on the
shaker is termed a matched resonant load, and it is purely
resistive since the force is in a phase with the velocity.
If the resonant load input is other than 30 lb : 30 in/s, the
full 50 watts of mechanical power cannot be delivered to the
structure, the system being either force or velocity limited.
If the resulting maximum response level is not great enough,
the user may have the option of moving the shaker to a drive
point having an impedance closer to the matched value, or
adding more shakers to the array driving the structure.
Within the limitations of maximum force and velocity, the
actual power delivered to a structure is a function of the input
mechanical impedance at the drive point. In typical modal
testing, this input impedance varies widely in magnitude and
phase angle. At different frequencies, the input impedance
of the drive point may appear predominately spring-like,
mass-like, or resistive. Since the object of the tests is to
establish resonant modes, at which the input mechanical
impedance of all drive points are resistive, the shakersmaximum performance capability is most meaningful stated
in terms of the force and velocity that can be obtained when
driving a matched resistive load.
Therefore performance is given in the form of graphs which
present the envelopes of maximum force and velocity delivered
to a resonant structure as functions of the resonance frequency
of the structure.
Another application is the excitation for sensor calibration.
Acceleration performance of the APS 113 ELECTRO-SEIS
with various mass loads is shown in the lower graph for the
30-Ib rating.

PERFORMANCE
The primary purpose of the Model 400 ELECTRO-SEIS
is to determine the dynamic characteristics of mechanical
structures. At resonance, a large amount of energy is
contained in the structure, and the shaker must accommodate
the resulting motion. However, it need only supply the real
mechanical power dissipated by damping mechanisms within
the structure.
If a drive point on a structure in resonance is vibrating
with a velocity of 30 in/s and a force of 100 lb is required to
sustain the vibration level, then the shaker will be delivering
approximately 170 watts to the structure. Such a load on
the shaker is termed a matched resonant load, and it is purely
resistive since the force is in a phase with the velocity.
If the resonant load input is other than 100 lb 30 in/s, the
full 170 watts of mechanical power cannot be delivered to the
structure, the system being either force or velocity limited. If
the resulting maximum response level is not great enough, the
user may have the option of moving the shaker to a drive point
having an impedance closer to the matched value, or adding
more shakers to the array driving the structure.
Within the limitations of maximum force and velocity, the
actual power delivered to a structure is a function of the input
mechanical impedance at the drive point. In typical modal
testing, this input impedance varies widely in magnitude and
phase angle. At different frequencies, the input impedance
of the drive point may appear predominately spring-like,

establish resonant modes, at which the input mechanical
impedance of all drive points are resistive, the shakers
maximum performance capability is most meaningful stated
in terms of the force and velocity that can be obtained when
driving a matched resistive load.
Therefore, performance is given in the form of graphs which
present the envelopes of maximum force and velocity delivered
to a resonant structure as functions of the resonance
frequency of the structure.

APS 0109Zero Position Controller for Vibration Exciters
Description
The APS 0109 Zero Position Controller automatically controls the zero position of a vibration exciter irrespective of itsload. It is essential to employ a position controller of type APS 0109 especially when working with an air-bearing vibra-tion shaker without any integrated automatic load-compensation. The control characteristics of the APS 0109 can beadjusted, so the Zero Position Controller APS 0109 can easily be adapted to different types of shakers in vertical orhorizontal operation directions. The Zero Position Controller contains a number of monitoring and control functions thatefficiently prevent any overload or damage of the connected system. The APS 0109 is intended for the automatic con-trol of vibration systems with integrated power amplifiers that supply an offset-free DC voltage.
The following functions are available:
Switching on and off regime controlled by microcontroller (soft start-up and shut-down)
Signal inputs will be connected through only after zero position has been reached
In case of error: system is shut down in a well-defined and soft manner
Monitoring of maximum vibration displacement Monitoring of air pressure in air-bearing shakers
Adjustable zero position
LED for indication of operating condition and protective function
The customer can opt between three types of optical position measuring systems. In this way, any interference by mag-netic fields (for example that of the shaker) is avoided. Because of its modular design, the APS 0109 can be configuredcost-effectively in line with the requirements of the entire system.
