Optimization Research of Multi-Point Response Control under Multi-Support Excitation in Vibration Test

Abstract:

As an important experiment way adopted in vibration test, response control method obtained more and more attention in recent years, this paper studied the multi-point response control under multi-support excitation in vibration environment test, deduced the transfer equation set between base control excitation and structure response. After analyzing these transfer equation set, the existence and uniqueness of base control excitation was discussed, and proposed an optimization method to solve these transfer equation set based on genetic algorithm (GA). The numerical simulation result indicates the validity of the proposed optimization method. These works provided a theoretical foundation for multi-degree of freedom vibration test in a certain extent.
