Dynamic Response Optimization Design of Structure with Reliability Constraints on Dynamic Stress and Displacement

讨论了随机参数结构在随机荷载激励下的优化设计问题 ,建立了具有动应力、动位移可靠性约束和设计变量上、下限约束的工程结构优化数学模型 ,并将可靠性约束等价显示化为常规约束 ,优化中采用复合形法求解。

The problem of optimization design of structure with random parameters under random loads is studied. The optimal mathematical model of engineering structure with the reliability constraints on dynamic stress and displacement and constraints on the upper and lower bounds of the design variables is built. A complex method is used in the optimization. The example illustrates the correctness and practicability of the optimal model and solving approach.
