Abstract
Response limiting capabilities of vibration controllers can be insufficient to compensate for lightly-damped structures with high Q values and narrow resonance skirts during high sweep rate sine sweep tests. Structures with these characteristics are common in the aerospace industry. This paper outlines and exhibits an automated method developed and validated cooperatively by M + P International and engineers at Harris Corporation to predict and compensate for response limit overshoots. The method employed utilizes data from lower-level sweeps to modify response limit tables. It has been demonstrated to be effective for linear structures with constant transmissibilities in terms of amplitude and frequency.
