对于厚壁筒形的结构,如装有电感应加热装置或核燃料的筒形构件,往往由于内部受热产生高的热应力。这种热应力是由筒形件内外表面之间高的温差引起的。当计算许多不同尺寸的这种圆筒形结构的热应力值时,其计算相当麻烦,也很费时间。但是,这种复杂的计算完全可以简化,本文介绍一种可借助一些包括标称数据的曲线图来确 For thick-walled cylindrical structures, such as tubular components equipped with induction heating devices or nuclear fuel, high thermal stresses are often generated due to internal heating. This thermal stress is caused by the high temperature difference between the inner and outer surfaces of the cylindrical member. When calculating the thermal stress values ​​for many different sizes of such cylindrical structures, it is computationally cumbersome and time-consuming. However, this complex calculation can be simplified, this article presents a graph that can be done with some nominal data
