摘要
借助大型有限元分析软件ANSYS,针对A型防尘密封圈(简称A型圈)大变形和非线性特征,建立以氟橡胶、丁腈橡胶、聚氨酯为基体的3种不同橡塑材料A型圈的非线性有限元分析模型,对3种材料A型圈进行了最大接触应力、平均接触应力及应力分布的分析对比。研究结果表明,A型圈唇部长度及唇尖厚度变化对接触应力及其分布形式有重要影响。
By using ANSYS software,according to nonlinear characteristics and large deformation of type A dustproof sealing ring,nonlinear finite element analysis models of type A dustproof sealing ring made of three kinds of rubber/plastic blends which were based on fluorine rubber,nitrile-butadiene rubber and polyurethane rubber,respectively,were established.The maximum contact stress,average contact stress and their distribution were analyzed and compared.The results showed that the change of the lip length and thickness of type A dustproof seals had significant influence on the contact stress and its distribution.
