| Abstract: | By means of analysis on temperature field of finite element and calculation of coupling number of temperature field and stress analysis, implements the stress calculation of finite element under the simultaneous action of temperature and pressure loads of shaped - tube sheet heat exchanger. By adopting stress classification and evaluation method of JB 4732 ?1995 "Steel Pressure Vessel?Analysis and design standard" to evaluate the analyzed result, implements stress analysis and evaluation under the actual structure finite element model of shaped ?tube sheet heat exchanger. |
