Electrodynamic Shaker Meets Battery Test UL 2231 (Shock, Vibration)

Electrodynamic Shaker Meets Battery Test UL 2231 (Shock, Vibration)

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.

Working Principle:

Specifications:

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.
