摘要：

为解决同轴磁场调制型磁齿轮在进行仿真设计时，模型计算量大及磁化方向设定工作繁琐的问题，提出一种采用直线模型代替原有常规圆环模型的简化设计方法。基于磁齿轮各部分结构和磁场的周期性，简化建模工作和减少仿真分析的计算量，结果表明：直线结构相较于圆环结构，充磁坐标系设定数量减少85%以上，磁齿轮的内环磁极数量超过4对时，单模型进行有限元分析的时间明显缩短，并且提升效果随磁极数量增加而更为显著。

Abstract:

To address the issues of large model computation load and cumbersome magnetization direction setting during the simulation design of coaxial magnetic field modulation type magnetic gears, a simplified design method is proposed, which uses a linear model to replace the original conventional circular ring model. Based on the periodicity of the structure and magnetic field of each part of the magnetic gear, the modeling work is simplified and the computational load of the simulation analysis is reduced. The results show that compared with the circular ring structure, the number of magnetization coordinate system settings for the linear structure is reduced by more than 85%. When the number of inner ring magnetic poles of the magnetic gear exceeds 4 pairs, the time for finite element analysis of a single model is significantly shortened, and the improvement effect becomes more significant as the number of magnetic poles increases.

Key words: coaxial magnetic gear, finite element simulation analysis, linear model, design simplification, field modulation
