一、概述波形膨胀节有许多形式,其中以U形膨胀节应用最广泛。膨胀节良好的补偿变形能力已被工程界所公认。从五十年代至今,各国对膨胀节的研究一直不断地进行着,发表了许多介绍理论研究及试验方面的结果,也推荐许多计算公式。总的来说,大致可分如下一些情況: 1.解析方法膨胀节实际上是由两只半环壳和环板组合而成。因此,可以以环壳和板的微分方程为出发点,通过解析方法寻求答案。有人得到了级 First, an overview of the waveform expansion joint has many forms, of which U-shaped expansion joint is the most widely used. Expansion joint good ability to compensate deformation has been recognized by the engineering community. From the 1950s to the present, the research on inflation festival has been continuously carried out by various countries. Many results of theoretical research and experiments have been published, and many calculation formulas have also been recommended. In general, the following can be broadly divided into the following situations: 1 analytical methods Expansion joint is actually composed of two half-ring shell and ring plate combination. Therefore, the differential equations of the shell and the plate can be used as the starting point to find the answer by analytical method. Someone got a grade
