摘要
文中介绍了某固定管板式换热器高温高压下的工作条件 ,建立了热分析与结构分析的有限元模型 ,计算得出管板的温度场以及温度场与结构耦合产生的应力场 。
Finite element models for a fixed tube sheet heat exchanger were established with considering the coupling action of high temperature and high pressure. Temperature and thermal stress distribution fields are obtained and analyzed for some important regions or along some critical stress check lines in the exchanger.
