C型波纹管纯弯曲刚度设计公式

The Stiffness Formulae of Pure Bencing for C type Corrugated Tubes

本文引用园环壳弯曲方程一般解,对C型波纹管在端部弯矩作用下变形进行了系统分析计算,提出了实际工程中刚度设计公式。并对精确分析与简化分析弯曲刚度的差异进行了研究,得出了简化分析刚度设计公式的修正式。从而可方便地将弯曲刚度设计转化为轴对称刚度设计。

In this paper, the design formulae of rigidity constant of C-type corrugated tubes under the action of edge bending moments are given. These formulae include the accurate formulae and amending formulae which are obtained by using simplified calculation. Using the amending formulae, the problem of axial stmmetry can simply take place of the problem pure bending for C-type corrugated tubes in the case of a slender ring-shell.
