摘要
为解决大型阻尼器工作中传统密封方式磨损老化维护困难问题,针对磁流变阻尼器的工作特点,在磁流变阻尼器中充分利用新型智能材料磁流变液的优异特性,建立一种新型的非接触式磁密封机制。探讨非接触式磁密封机制的工作原理和具体结构,使用有限元仿真软件对阻尼器工作部位磁场进行仿真分析,建立磁密封理论耐压能力的理论计算模型。表明此种非接触式磁密封较传统密封方法具有高可靠性,超长维修间隔时间,摩擦小,效率高,无方向性的优势。
In the magneto-rheological damper,based on the well characteristics of the new intelligent material-magneto rheological fluid,a new non-contact sealing mechanism has been developed in order to solve maintenance problems of traditional large size damper caused by aging and wear process.After working principle analyzing and structure designing,electromagnetic finite element analysis has been employed to simulate and analyze the magnetic circuit,and a theoretical computation model for enduring magnetic sealing pressure has been established,which is proven that this magneto-rheological fluid sealing arrangement has its significant advantages comparing with traditional sealing mechanism with higher reliability,longer interval time of breakdown maintenance,lower friction and higher efficiency.
