摘要：
On the base of traditional robust optimal design in statics, in this paper, by considering the system under the incentive force of the arbitrary time function, the dynamic response robust optimal design problem, when system dynamic response can only be calculated using numerical integration. Considering the environmental interference factors in a system, derived the expression of response with a small parameter perturbation finite element method. Through the tiny fluctuation frame system in a post and beam's elastic modulus, realize the robust optimal design of the structural dynamic response, and using New-mark method for dynamic analysis, robust optimal design is applied in dynamic response optimization. Compared to the traditional optimal design's result in a frame system, robust optimal design of the frame displayed a significant improvement in performance.
