| 摘 要： | 将新型开关磁阻(SR)电动机应用于电动汽车.以电机为振源,分析其激振力在特定方向上的作用情况.用解析的方法,给出了径向力和切向力随时间变化的具体表达式.分析过程中,不仅考虑了SR电机径向力作用.而且考虑了切向力(转矩波动)对整个系统的影响.经过数值分析,得出在竖直方向上激振力的幅值与初相角有直接的关系,并且幅值存在最大值和最小值,提出了最大值和最小值的确定方法.通过算例,验证了整个分析的正确性.

| Abstract: | New type of switched reluctance motor was applied to electric vehicle. Considering the electromotor as vibration source, stimulation of electromotor was analyzed in particular orientation. Expressions of radial force and torque variance were obtained by analytical method. During the course of system analysis of electric vehicle and SR electromotor, both radial force of SR electromotor and torque variance were considered. It was concluded that there are direct relationships between amplitude and initial phase in vertical orientation by numerical analysis. There are maximum and minimum of amplitude, and the way to ensure them was proposed. New reliable foundation was put forward to solve vibration problems of design and control of SR electromotor. |
