| 摘 要： | 永磁涡流联轴器的涡流损耗对联轴器的性能有很大的影响,因此对永磁涡流联轴器的涡流密度进行研究具有重要意义。首先对永磁涡流联轴器的工作原理进行简单的介绍,然后确定有限元分析的结构参数并进行分析,再利用Ansoft进行有限元分析,研究不同气隙厚度、轭铁厚度、永磁体厚度、铜环厚度和占空比对涡流密度的影响。研究结果表明磁铁厚度、占空比和气隙厚度对涡流密度产生重要影响,而轭铁的厚度和铜环厚度对涡流损耗影响较小,这为永磁涡流联轴器的研制提供了重要参考依据。

| Abstract: | The vortex current losses of permanent magnet vortex coupling have great influence on the performance of the coupling,so it is of great significance to study the vortex current density of the permanent magnet vortex coupling. First, the working principle of the permanent magnet vortex current coupling is introduced briefly, and then the structural parameters of finite element analysis are determined and analyzed. And using Ansoft finite element analysis was carried out to study the influence of the different air gap thickness, the yoke thickness, the permanent magnet thickness, the thickness of the copper ring and the duty ratio on the vortex current density. The research results shows that the thickness of magnet, the duty ratio and the air gap have an important influence on vortex current density, while the thickness of the yoke iron and the copper ring have less influence. It can provide references for the further research of permanent magnet vortex current coupling. |
