The invention discloses a structural topology optimization simulation method based on dynamic response, and belongs to the field of structural optimization design. The method comprises the steps that a three-dimensional model is preprocessed, and a solving area and a non-solving area are divided; establishing a finite element simulation model, respectively endowing a solving region and a non-solving region with different attributes, and giving boundary conditions; performing dynamic response parameter optimization definition, and setting an optimization target and constraint conditions of optimization analysis; performing dynamic optimization calculation to obtain a solution result of the optimization target; and optimizing and verifying the structure three-dimensional model. The problem that in the prior art, due to the fact that statics conditions are adopted for optimization, the structure cannot bear complex dynamic environments such as vibration and impact for a long time is solved. 本发明一种基于动力学响应的结构拓扑优化仿真
