High Frequency Vibration Test Machine Meets MIL-STD ISTA Standard

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

System Force Rating

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.
