Force Limited Vibration Testing

M+P International ( UK ) Ltd News and PR from M+P International ( UK ) Ltd - Published 18 October 2017 m+p VibControl shaker control systems from m+p international have proved highly successful for force limiting vibration testing, thus effectively protecting test items against overtesting.
Force limited vibration testing (notching) limits the upper vibration level on any number of control or measurement channels, thus effectively protecting test items against overtesting. Overtesting occurs when vibration tests subject a test item to unrealistically severe – and potentially damaging – forces arising at resonances present in the component or fixture.

The m+p VibControl vibration control systems from m+p international have proved highly successful for force limiting vibration testing. During tests, the m+p system applies a predetermined sine or random vibration excitation to the assembly, but this is limited if the sum of individual forces in the excitation axis, the root sum square of the acceleration vector at each point, or the overturning moment exceed their set limits.
m+p international provides vibration control systems for effective force limited vibration testing to avoid overtesting.
