Abstract

Abstract: A new method is set forth in the paper for generating the driving signals for random vibration tests. Therandom driving signal sequence can be obtained by linearly filtering to the white noise sequence using finite impulseresponse (FIR) filters. A forming method of the FIR filters is introduced and an example is presented to show the effects of the method. The results are satisfactory. The FIR filters system can also be combined with the structure tobe controlled to form a broad system. It will simplify the analysis and design to the whole control system with thebroad system.

Key words: random vibration test, vibration control, FIR filter
