| 摘 要： | 对于有密封要求的液压作动筒而言,O形密封圈在其中起到重要的作用。首先针对液压作动筒中的活塞密封结构,提出一类新的有限元分析模型,然后利用ANSYS软件研究O形圈密封结构在不同油压和压缩率作用下的应力分布及接触压力分布,并将有限元结果与以往的模型进行对比,总结每类模型的适用条件。新的有限元分析模型考虑了实际安装过程对密封圈的影响,对密封圈的安装具有指导意义,也为密封圈的动力响应分析提供了较好的模型。

| Abstract: | O-ring plays an important role in the hydraulic actuator with sealing requirement. Firstly, a new finite element analysis model for piston seal structure in the hydraulic actuator is established. Then, the distribution of the stress and contact pressure in the O-ring under different pressures and compression ratios are studied and compared by the software ANSYS. Meanwhile, suitable conditions for those models are given. The influence of installation process is considered in the new model, which has a guiding significance for the installation of O-ring and provides a preferable model for the dynamic analysis. |
