摘要
针对密封元件的材料、几何、状态的高度非线性使得密封圈变形较大且有限元分析计算过程不易收敛的问题,对影响Y形圈模型计算收敛性的关键因素进行分析,并对刚-柔接触模型的重要参数进行解析和选择,最终提出了理论上较为合理的Y形圈初始有限元模型的建模方法,即活塞杆轴向移动挤压Y形圈得到Y形圈的有限元初始模型.
Aiming at the problem which the deformation of seal ring is heavy and the finite element analyzing and computational process is difficult to convergence due to the high nonlinearity of material, geometry and status of the sealing element, a kind of more reasonable method in theory for getting initial finite element analysis model is come up by analyzing the key factors affecting the convergence property during solving process and choosing the important parameters of rigid-deformable contact model. That is, the piston rod moves axially and compresses the Y-ring, and then gets the initial Y-ring model.
