一、引言将结构分析的基本理论与优化方法结合起来应用于工程设计,不仅能让设计人员摆脱烦琐、枯燥的手工计算,加快设计周期,更重要的是彻底改变了传统的校核性设计方式,积极主动地寻求满足强度、刚度等约束条件的最优方案,从而使设计成品尽可能做到经济、合理、可靠。目前,有关优化方法的理 I. INTRODUCTION Combining the basic theory of structural analysis and optimization methods into engineering design not only frees designers from cumbersome and tedious manual calculations, speeds up the design cycle, but more importantly, completely changes the traditional design method of calibration. , Proactively seek the optimal solution that satisfies the constraint conditions such as strength and stiffness, so as to make the finished product as economical, reasonable, and reliable as possible. At present, the rationale for optimization methods
