The effect of parameter distribution pattern on frequency response localization in nearly periodic systems

초록

In a mechanical system that has periodically repeated subcomponents, premature failures or malfunctions often occur. Due to slight irregularities of parameters of periodic systems, maximal frequency responses of a few subcomponents become often significantly larger than those of other subcomponents. These phenomena, called frequency response localization, need to be comprehended for reliable designs of the periodic systems. In the present study, the effects of parameter distribution patterns on the frequency response localization are investigated. Probabilistic results of the frequency response localization characteristics with two distinct parameter distribution patterns are exhibited.
