摘要
设计了一种新型的阻尼可控磁流体滑动轴承,为了探究外加电流与工作区域磁感应强度的关系,验证该轴承磁路设计的合理性,利用有限元分析软件ANSYS对磁流体滑动轴承的磁场模型进行了分析并搭建了磁场发生器磁场测试系统,通过理论研究和实验测试,对比分析了磁流体滑动轴承内部的磁场强度。结果表明,工作区域的磁感应强度B与外加电流强度I成正比;该轴承内部的磁力线分布均匀,实验结果与仿真结果相吻合,验证了磁流体滑动轴承设计的合理性。
A new type of damped controllable magnetic fluid sliding bearing is designed.In order to explore the relationship between the applied current and the magnetic induction intensity in the working area,and to verify the rationality of the magnetic circuit design of the bearing,The magnetic field model of magnetic fluid plain bearing is analyzed by using finite element analysis software ANSYS,and the magnetic field test system of magnetic field generator is b u ilt.The experimental results are compared and analyzed.The results show that the magnetic induction intensity B in the working area is proportional to the applied current intensity I.The magnetic field distribution of the bearing is uniform and almost all the magnetic force lines pass through the working clearance of the magnetic flu id.The experimental results are in good agreement with the simulation results,so the magnetic circuit design of the sliding bearing designed in this paper is reasonable.
