摘　　要：为了有效改善传统密封材料的密封特性,介绍了磁性橡胶作为中高压密封件的密封机理及可行性。研究发现:由于磁性橡胶具有摩擦系数小,硬度高等特点,密封圈的使用寿命以及使用质量得到改善,密封效果得到有效的提高。使用磁性油封能够避免油封发生老化造成唇口磨损、弹性变坏以及应力松弛,Fi逐渐降低等缺点。利用有限元软件Ansys对其进行了分析,对使用以及安装磁性橡胶O形圈时,在密封界面之上产生的接触应力的分布规律以及接触变形展开了分析,并与普通密封圈进行了对比,在理论上给橡胶O形圈提供了进一步优化以及可靠设计的依据。In order to improve the seal characteristics of the traditional sealing material,the seal mechanism of the magnetic rubber used in the mesohigh sealing is introduced in the paper.It is found that the quality in use,sealing effectiveness and service life of the seal ring are improved due to the low friction coefficient and high hardness of the magnetic rubber.And the elasticity variation,stress relaxation and lips mouth wear,which lead to Fi is reduced,are prevented due to the magnetic rubber used in sealing.The distribution rule of the contact stress and contact deformation of the magnetic O sealing ring in installation and use is obtained by using the software Ansys,which provides a foundation for the further application.
