Abstract: Improved multi-object genetic algorithm (IMGA) is used to study the matching technique of shock response spectrum (SRS). The improvements include using priority objective-active mechanism, building control group, selecting individual by the priority and distributing, unitizing parameters, and searching in chaos. Considering the practical need, a wavelet synthesis method is used to compute and optimized result is obtained. Simulation shows that IMGA is highly applicable and practical in the matching technique of SRS.

Key words: shock response spectrum (SRS), genetic algorithm (GA), matching, wavelet synthesis
