CE / ISO Electrodynamic Vibration Exciter Modal shaker Table For
Laboratory Test
Dynamic Shaker Vibration Testing Machine simulates the vibration environment under the laboratory
condition, and test the impact strength as well as reliability of
various vibration test applications. In the laboratory, with the
aid of vibration testing system, model simulation of reproduction
of sinusoidal, random, resonant search and dwell, classical shock
and road simulation, etc. can be achieved. It is essential for
product quality assurance, new product research and development.
Force = Mass x Acceleration (F = MA)
In general, the selection of a vibration system requires
application of Newton’s Second Law of Motion: Force = Mass x
Acceleration (F = MA). But this basic formula is only a starting
point. It may be instructive to describe one example of an incorrect approach to estimating the required system force rating.
Example: “I have a 50 lb test specimen that must be tested @ 10 g.
Therefore, I need a vibration system rated at 50 x 10 = 500 lbs
force.”
After reviewing the following technical discussion you will have a
better understanding of why this estimate of system force is
incorrect
Vibration systems have output force ratings typically expressed in
terms of:
- Sine force: lbs (kN) pk
- Random Force: lbs (kN) rms
- Shock Force: lbs (kN) pk
The stated random force rating assumes a certain spectrum shape
(usually flat) over a given frequency range (usually 20 Hz – 2,000
Hz) and a certain minimum mass load on the shaker. If these
conditions are different from your test requirements, a new
calculation of the effective random force rating may be necessary.
These output force ratings provide a starting point for the Force
(F) parameter in F = MA.
