工业上使用的压力容器和传热设备内的热流体使其内外壁之间产生较大的温度梯度,这将引起温度应力。 运用精确的数学分析方法,可以求出具有极对称温度分布的球壳内的径向、切向应力。但是,这种精确的方法需要进行许多复杂的运算。相反,这里介绍的标准曲线,能够用来求出温度应力的相应分量,其计算精度对于设计初期的估算是足够的。 Industrial use of pressure vessels and heat transfer equipment inside the hot fluid to make a large temperature gradient between the inner and outer walls, which will cause thermal stress. Using accurate mathematical analysis, we can find the radial and tangential stresses in the spherical shell with the symmetrical temperature distribution. However, this exact method requires many complex calculations. On the contrary, the standard curve introduced here can be used to find the corresponding component of temperature stress, and the calculation accuracy is enough for the initial design estimation.
