阀门热应力分析与研究

Thermal stress analysis and study of valves

介绍了压力容器的压应力与热应力关系,使用优化分析方法确定了耦合应力作用下的压力容器最小壁厚。探讨了阀门热应力载荷的施加方法。

The relation between compressive stress and thermal stress is described.And the minimum wall thickness under coupling stress is given through the optimal analysis.Meanwhile,this thesis also makes a comparative analysis for the application method of thermal load.
