锥壳基础优化设计

Optimazation design of the cone shell foundation

对承受集中载荷的锥壳基础进行塑性分析.令锥壳的壁厚为设计变量,把基础优化设计问题归结为求泛函极值问题.并对实际工程中常见的线性变厚和径向具有加强肋的锥壳进行了最小重量设计方法的研究.试验证明.这些方法对塑性材料结构具有很好的工程精度.

This paper makes plastic analysis foundation of the cone shell under concentra- tion load.The problem of optimazation design of cone shell foundation is sumed up in the problem solving the extreme value of functional.The method of mini- mum weight design of the cone shell in common engineering is studied.
