摘　　要：以某水面无人艇配备的电动舵机为研究对象,针对由永磁同步电机电磁激励引起的电动舵机电磁振动展开了分析。建立了永磁同步电机的电磁场模型、电动舵机的结构模型和谐响应模型。从电磁激励、模态特性及振动响应3方面对电磁振动进行了仿真分析,研究影响电磁振动的因素以及在这些因素作用下的振动响应。仿真结果表明,在电磁激励幅值较大的频率和舵机的模态固有频率处,振动响应存在峰值。The paper studies on the vibration of an unmanned underwater vehicle,which is stimulated by the changing electromagnetic field of the permanent magnet synchronous motor(PMSM).Electromagnetic model of the PMSM,structural model and harmonic response model of the electrical actuator is built for simulation of electromagnetic vibration on three aspects.It is shown that there are vibration peaks at frequencies where electromagnetic stimulation is relatively tense and peaks at frequencies coupled with natural frequencies of the actuator.
