摘要
Abstract
The basic principle of structural coupled thermal stress calculation by finite element method was demonstrated in this paper,and the solving equation of transient temperature field and the solution method of the coupled thermal stress were listed.The finite element method’s implementation and analysis of transient temperature field and coupled thermal stress in a pressure vessel were emphatically discussed.On the basis of reasonable simplification to the actual structure,the time-dependent curve of structural transient temperature and coupled thermal stress was obtained,and the stress distribution of the integral structure and the main bolt at the end of the temperature rise were also given.关键词
