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

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

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.
