应用 ANSYS 软件对固定管板式换热器管板进行应力分析，得到管程压力，壳程压力和热载荷三个不同工况组合下管板的应力，并根据 JB4732-95《钢制压力容器-分析设计标准》对危险截面进行应力强度评定。分析结果表明，管板的强度满足要求，此文的研究方法为同类型换热器安全评估提供了参考。
應用 ANSYS 軟件對固定管闆式換熱器管闆進行應力分析，得到管程壓力，殼程壓力和熱載荷三箇不同工況組閤下管闆的應力，併根據 JB4732-95《鋼製壓力容器-分析設計標準》對危險截麵進行應力彊度評定。分析結果錶明，管闆的彊度滿足要求，此文的研究方法為同類型換熱器安全評估提供瞭參攷。

The stress of tube-sheet heat exchanger was analyzed by using the ANASYS software, the stresses of tube-sheet under three different load conditions of tube side pressure, shell pressure and thermal load were obtained, respectively. According to the JB4732-95 Steel pressure vessels-the standard of analysis design, the strength of the dangerous sections was assessed. The analysis results indicated that the intensity requirement of the tube-sheet was satisfied. The paper can provide the reference for the safety assessment of the heat exchanger in service.
