摘要
以提高磁粉离合器转矩容量为目的,在深入研究其工作机理的基础上,利用虚位移电磁力计算理论推导得出了转矩传递公式;以麦克斯韦方程为磁场分析的理论基础,建立了磁粉离合器二维有限元分析模型并进行了计算,仿真结果与试验结果吻合;根据仿真分析结果,对其进行了改进设计,改进后的磁粉离合器转矩性能提高了45%。
To increase the torque capacity,the torque-transferring formula was deduced from electromagnetic force theory of virtual displacement according to working mechanism of magnetic particle clutch.The FEM model was established based on theory of Maxwell equation for analysis magnetic field and its simulation results conformed to the test results.According to the simulation results,improved design was made on magnetic particle clutch.The results showed that the improved magnetic particle clutch had a remarkable effect on the torque performance,and its torque performance increased by 45%.
