目前,有关波纹管刚度的计算公式尚没有统一,国内外所采用的公式有几种,使用时往往各循其规。为了有一个比较统一的计算方法,我们对常用的几种公式进行了实验评价。一、几种常见公式1.费奥多谢夫公式:K=Eo_0/(1-μ~2)n(A_0-A_1α+A_2α~2+B_0 δ_0~2/R_B~2)式中:E—材料的弹性模量;μ—材料的泊桑系数; At present, there is no uniform formula for calculating the stiffness of corrugated pipe. There are several kinds of formulas adopted at home and abroad, and the rules are often used when they are used. In order to have a more uniform calculation method, we have carried on the experiment appraisal to the commonly used several formulas. First, several common formula 1 Feodoshev formula: K = Eo_0 / (1-μ ~ 2) n (A_0-A_1α + A_2α ~ 2 + B_0 δ_0 ~ 2 / R_B ~ 2) Where: E-material Of elastic modulus; μ-material Poisson coefficient;
