摘　　要：通过建立反应堆压力容器的二维ANSYS有限元模型,考虑不同温度下的材料性能变化,计算了压力容器在不同温度下的热应力和压应力耦合时的应力强度,以及标准工作状态下的爆破压力,根据模拟结果得出温度与应力强度之间的关系。In this paper, the stress intensity of pressure vessel under the coupling effect of thermal stress and pressure stress at different temperatures is ealculated through establishing a twodimemional model of the pressure vessel by the finite element saftware ANSYS and considering the changes of material properties at different temperatures, as well as the burst pressure under the standard state. The relationship between the temperature and the stress intensity is derived according to the simulation results.
