General Solution for U-Shaped Bellows Overall-Bending Problems

Shanghai Institute of Applied Mathematics and Mechanics, Shanghai University Shanghai 20072, P R China

摘要

摘要: 利用朱卫平等提出的柔性细环壳整体弯曲的一般解和相应的环板方程的解给出了U型波纹管在子午面内受纯弯矩作用整体弯曲的应力分布和转角公式。把计算的结果和按EJMA(Stan-dardsofthe Expansion Joint Manufacturers Association)计算的结果以及黎廷新等的实验结果作了分析比较。

Abstract: The formulae for stresses and angular displacements of U-shaped bellows overall bending in a meridian plane under pure bending moments are presented based on the general solution for slender ring shells proposed by Zhu Weiping,et al.and the solution for ring plates.The results evaluated in this paper are compared with those on EJMA(standards of the expansion joint manufacturers association) and of the experiment given by Li Tingxin,et al.
