Optimization Design of Magnetorheological Damper for Machine Tool Vibration Reduction

以三平动冗余驱动并联机床为研究对象,设计了一种具有位移放大功能的磁流变阻尼器,通过Ansys workbench有限元分析软件,对阻尼器的磁路饱和情况进行模拟仿真和分析,使阻尼器的阻尼出力达到最优。研究结果表明,通过优化使磁场分布更加合理,提高了阻尼器的力学性能,优化方法是可行有效的。

This paper takes the three-way redundant drive parallel machine tool as research object,designs a magnetorheological damper with displacement amplification function and simulates the magnetic circuit saturation of the damper by the Ansys workbench finite element analysis software,so that the output of the damper comes to optimization.The research results show that the magnetic field distribution is more reasonable,and the mechanical properties of the damper are improved.The optimization method is feasible and effective.
