摘　　要：将样条子域法与惩罚函数法结合 ,应用于薄壁结构设计 ,形成了一种结构分析合理、计算量较少、适用于各种不同约束条件、便于微机处理的薄壁结构优化方法 .实例计算表明这种方法在薄壁结构优化设计应用中具有实用价值 .An optimal method, which combines the semi analytical numerical method (splint sub domain one) with the optimization design (penal function one), is proposed for the design of the thin wall structure. It is rational in structural analysis and computer language, able to be applied to various restrained and subjected conditions. It is also very easy to be accepted by engineers and can be run in a microcomputer. Numerical examples show that this proposed method is practicable in engineering the optimization design of the thin wall structure.
