摘要
研究挤压成型波纹管机械密封中波纹管的轴向刚度及应力状态,将有限元计算与采用工程实际经验公式的计算结果和该波纹管的试验结果进行了比较。同时通过建立的波纹管有限元模型,分析了外压作用下波纹管结构对波纹管的应力状态的影响。
In this article, the research of axial stiffness and stresses distribution of extruded metal bellow tube used in mechanical seal was carried out, and the results from finite element analysis, empirical engineering equation and test were compared. Through establishing the finite element model of bellow tube, the influence of the structure of bellow tube, which is subjected to external pressure, to the stresses distribution was also analyzed.
