摘　　要：结合行星齿轮系统的横向扭转特性研究分析了电机-齿轮系统机电耦合模型的动态特性。通过电机-齿轮系统进行机电耦合动力学仿真,对磁网络模型机电系统的响应与动态电机模型机电系统的响应进行了比较,分析了负载和空载状态下两系统的转矩、电流以及转速频谱特性。研究了磁饱和效应对机电耦合系统的动态特性影响,在忽略饱和效应时,机电耦合系统的动态啮合力频谱没有显著变化,在考虑磁饱和效应下,转矩频谱中存在由饱和效应引起的次谐波频率,但负载时,啮合力和转速频谱不会受到显著影响,同时分析了轴刚度对动态啮合力的影响,对优化机电耦合动态特性具有重要作用。Combined with the lateral torsional characteristics of planetary gear system,the dynamic characteristics of electromechanical coupling model of motor gear system are studied and analyzed. Through the electromechanical coupling dynamics simulation of motor gear system,the response of PNM model electromechanical system is compared with that of dynamic motor model electromechanical system,and the frequency spectrum characteristics of torque,current and speed of the two systems under load and no-load conditions are analyzed. The influence of magnetic saturation effect on the dynamic characteristics of electromechanical coupling system is studied. When the saturation effect is ignored,the dynamic meshing force spectrum of electromechanical coupling system has no significant change. Considering the magnetic saturation effect,there is subharmonic frequency in the torque spectrum caused by saturation effect,but under load,the meshing force and speed spectrum will not be significantly affected. At the same time,the shaft stiffness response is analyzed. The influence of state engagement force plays an important role in optimizing the dynamic characteristics of electromechanical coupling.
