内压—压缩位移载荷作用下U形波纹管平面失稳判据的应用研究

Research on Application of Criterion in the In-Plane Instability of Non-Reinforced U-Shape Bellows under Internal Pressure and Displacement Loads

本文在U形无加强波纹管平面失稳判据研究的基础上 ,对内压和轴向位移载荷作用下不锈钢波纹管的平面失稳临界工况线 ,采用了作图法和参数拟合方法加以简化 ,使之能够应用于工程设计。

The diagram and fitted model is presented to simplify the critical behaviour curve in the in-plane instability of stainless steel bellows under internal pressure and displacement loads,in accordance with the research on criterion in the in-plane instability of non-reinforced U-shape bellows.
