摘　　要：本文以高温722℃条件下的镍基管板为研究对象,采用本构关系等效的方法,利用二维轴对称模型,对管板承受的热应力进行分析计算,并对计算结果进行评定,为后续采用二维模型计算高温管板的热应力提供方法参考。In this paper,the thermal stress of tube sheet with the material of nickel alloy under the condition of the temperature 722℃ is computed by two-dimensional axisymmetric model,and the evaluation of the thermal stress is executed.The equivalent constitutive relation method is used in the analysis.So,it provides a reference for calculating the thermal stress of tube sheet which is operating at the high temperature condition with two-dimensional model in further design of tubular heat exchanger.
