To study the influence of O-rings secondary seals, deformation behaviors of mechanical seal faces were analyzed under different pressures with the method of integral contact analysis by FEM.
采用整体接触有限单元法，考虑“O”型辅助密封圈的影响，计算了不同压力下机械密封端面变形行为。
There are fewer applications currently in the domestic. This article focuses on the analysis methods, the influence factors and its solutions as well as the applications of GC-O.
目前国内应用较少，文中简要介绍了GC-O法的分析方法、影响GC-O分析的因素及解决途径和其应用。
