摘要
通过ANSYS软件进行磁场仿真得出了不同磁流体通道间隙,磁极长度,磁极形状以及磁回路厚度下磁流变阻尼器磁感应强度随时间变化的曲线图。通过分析磁场仿真结果得出:随着磁流体通道间隙的增加,其响应时间呈上升趋势;随着磁极长度的增加,其响应时间减小;磁极表面有不同形状,当磁极表面形状为平面且有圆弧倒角时其响应时间最短;活塞磁场未饱和时,随着磁回路的厚度的增加其响应时间增大,当活塞磁场饱和时,磁回路的厚度对磁流变阻尼器的响应时间不会产生影响。
The simulation of magnetic field with ANSYS software is carried out to obtain the curve diagram of the magnetic induction intensity of the magnetorheological damper under the conditions of different magnetofluid channel gaps,magnetic pole length,magnetic pole shape and magnetic loop thickness.The simulation results show that the response time of the magnetorheological damper increases with the increase of magnetic field and that the response time decreases with the increase of magnetic pole length.The response time is the shortest when the shape of the magnetic pole surface is flat and there is an arc chamfer.When the magnetic field of the piston is unsaturated,the response time increases with the increase of the thickness of the magnetic circuit,but when its magnetic field is saturated,the thickness of the magnetic loop has no effect on the response time of the magnetorheological damper.
