【Abstract】 In this paper, the state equation is used to describe the dynamic chara-cteristics of mechanical systems and to deal with design variables and state variables directly. Based on the analysis of sensitivity for adjoint variables, the gradient projection algorithm in nonlineal programming is extended to the optimization of function space and the state space gradient projection algorithm is established, which is applied to the optimal design of the CS-131 light vehicle suspension. The results show that the method proposed in this paper is well suited fol the optimal design of mechanical systems subjected to transient dynamic loads.更多还原
