| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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 thick-ness of type A dustproof seals had significant influence on the contact stress and its distribution. |
