内压厚壁圆筒体最大允许内外壁温差的研究(上)

Study of the maximum allowable temperature difference for thick wall cylindrical shell under inner pressure (Part Ⅰ).

通过给内压引起的圆筒应力分类和评定 ,对圆筒在内压作用下的各向应力沿应力处理线进行均匀化处理。同时 ,分外加热和内加热两种情况 ,对径向温度梯度作用下圆筒中的热应力沿应力分类线进行当量线性化处理 ,给出了相应的计算公式。

By means of classification and evaluation of the stress on the cylinder under internal pressure, the stresses on the thick wall cylindrical shell in all directions are linearized. In addition, the thermal stress on the cylinder is also linearized along the stress classification line under radial temperature gradient according to whether the cylindrical shell is heated from the outer surface or the inner surface. Relevant calculation equations are presented.
