基于Ansys Maxwell的电磁式磁滞张力器仿真分析

Simulation and Analysis of Electromagnetic Hysteresis Tensioner Based on Ansys Maxwell

介绍一种磁滞张力器的结构和工作原理,借助Ansys Maxwell软件的静态、瞬态场求解器对张力器的磁场分布进行了数值计算,得到了张力器内部的磁力线走向以及转子表面的磁感应强度分布云图,研究了电流、磁极相对角度、气隙等参数对磁滞转矩大小的影响。遵循单一变量原则,得出各影响因素在各自变化范围内的最优解,为后续对该类型张力器的设计制造与升级优化提供了依据。

The structure and working principle of a hysteresis tensioner is introduced.The magnetic field distribution of the tensioner,with the help of the static and transient field solver of Ansys Maxwell software,is numerically calculated,and the distribution cloud map of magnetic trend in tensioner and magnetic induction on rotor surface is abtained.The influence of current,magnetic pole relative angle,air gap and other parameters over the hysteresis torque is studied.By following the single variable principle,the optimal solution of each influencing factor within the range of variation is obtained,which provides the basis for the subsequent designing,manufacturing and optimization of the tensioners of the same type.
