Performance of Dynamic Shaker
The maximum acceleration level of an electromagnetic shaker is determined by the maximum current and the loading condition. At low frequency, displacement of moving part is limited such that the acceleration will not reach high level. The resonance frequency of the moving element is designed to be higher than the upper limit of the frequency range of the shaker.
Selection of Shaker Model
To choose a suitable vibration test system, the most important thing is to know the exciting force required to perform the vibration test. To evaluate and calculate the exciting force, the following data should be specified:
The specimen fixation is selected based on the upper limit of test frequency and specimen size, either vertical expansion platform or horizontal slip table. Specimen mass is needed to evaluate the required exciting force for vibration test.

FAQ:
How do you attach the hardware you’re testing to your shaker?
By means of a fixture, usually aluminum or magnesium for lightness
coupled with rigidity. They can be cast, or smaller fixtures
machined from solid stock. Most fixtures are welded.
How do you control shakers?
If we’re looking for resonances in the product we’re testing, we
command the shaker to shake the product at one frequency at a time
but to vary that test frequency, to sweep it over a range of
frequencies.But more realistically, we command the shaker to
vibrate randomly and to excite all the resonances
simultaneously.Control commands go into the keyboard of a
specially-programmed computer.
What are those resonances?Are they bad?
Have you ever noticed the steering wheel moving with rather large
displacement amplitude, larger than the input to the column? That
magnification is called resonance. Possibly it annoys you. There’s
a slight chance that in a few years that whipping of the steering
column might cause bending fatigue failure.When we shake an
automotive or ship or land vehicle instrument, we're looking for,
for example, portions of printed wiring boards (PWBs) responding
with greater motion than we're inputting. That flexing may damage
PWB wiring, it may damage the attached components, and it will
damage the soldered connections between components and the PWB.
