【Abstract】 In this paper,an effective two-dimensional structure optimization and reliability design method is proposed. The reliability design method is used in the optimal design of practical engineering structure. The example of calculating the engine link bar showed that the combination of finite element method, optimization method and reliability analysis will be an effective way to design engineering structure and get light ,reliable and economic structures. It will help to improve the design level of engine structure.更多还原
