大规模板结构优化齿行法

A Zigzag Method for the Optimization of Large-Scale Plate Structures

利用Ｋｕｈｎ－Ｔｕｃｋｅｒ条件，导出了以板厚度为设计变量的单位移约束板结构优化准则，提出了板结构优化齿行法，导出了相关公式。数值结果表明，这一方法收敛快、稳定性好，可用于大规模板结构优化或组合结构优化．

A new zigzag method for the optimization of plate structures is proposed and optimumcriteria for plate structures with a singal displacement constraint from Kuhn-Tucker condi-tions are derived.Numerical results show that the new method gives stable and repid coriver-gence and can be used for the optimization of large-scale structures and built up structures.
