As a fundamental parameter for describing shock effect, shock response spectrum has been extensively applied in the formulation of dynamic environment and response analysis. It is significant in test simulation and response analysis to synthesize time domain signals from the shock response spectrum. Genetic algorithm has been used in time domain synthesis for shock response spectrum. Time domain synthesis has been transformed into the optimization problem by using the basic function and comparing the shock response spectrum with the design level. Global optimization merit of genetic algorithm has been adapted in the parameter optimization to get the result in accordance with the error bound, with the relevant example being given as well.
