|
摘要
介绍一种基于传统叶片式液压减振器设计的叶片式MRF减振器的工作原理,提出两种结构方案.利用ANSOFT电磁场分析软件对两种不同方案的减振器进行磁场有限元分析,得到磁场分布相对比较理想的一种方案.采用磁场有限元分析的方法对叶片式MRF减振器的结构设计进行优化,可以有效提高减振器的性能.表明有限元分析方法在磁流变液减振器磁路设计中具有重要的应用价值.
The principle and two structure schemes of vane MRF damper designed base on conventional vane hydraulic damper are presented.Magnetic field finite element analysis of two different schemes of dampers is conducted through ANSOFT and then a scheme relatively ideal in magnetic field distribution is obtained.Additionally,optimization in structure design of vane MRF damper is completed by using the method of magnetic field finite element analysis,which will effectively enhance performance of damper.The result indicates that this method is valuable in magnetic circuit design.
