Problems of U-Shaped Bellows with Nonlinear Deformation of Large Axlsymmetrical Deflection(Ⅰ)——Counting Nonlinear Deformations of Ring Shells and Compressed Angle of Bellows

Shanghai Institute of Applied Mathematics and Medhanics, Shanghai University of Technology, Shanghai

摘要: 本文是文献[1、2]工作的继续,在以下方面作了发展:考虑了内、外圆环壳中面法线的中小转动变形(转角的平方与应变是同阶小量);计及了压缩角.计算结果与实验符合良好.本文方法对波纹壳的设计计算有实用价值,有关压缩角对特征关系影响的讨论有助于工程设计.

Abstract: This paper is a conrinuous study of papers [1,2].There is some progress in dealing with moderately small rotations of middle surface normals of inside and outside ring shells and compressed angle of bellows.Calculation results agree with experiments well.To bellow design,the method given in this paper is of practical value and the discussion of the influence of compressed angle on characteristic relation is helpful.
