| 摘 要： | 本文提出了一种不须先求物体的温度场即可直接求出热应力的新方法。由此法得出的计算公式与经典方法相比,结果完全相同,但更为简便。文中应用该法并采用拉格胡日乘子法对椭园板的定常热应力进行了分析。表明所提出的方法对截面较为复杂的物体的热应力计算是更为可取的。

| Abstract: | This paper presented a new method which can directly obtain the thermal stress of a body without calculating the temperature field. Compared with the classical method, the formula in this paper are simpler and more convenient and the results are same. Using this method and adopting the Lagrangian multiplier method, the stationary thermal stress of the elliptical plate are analyzed. It shows that this method is more available for calculating the thermal stress of the complex cross section of a body. |
