摘　　要： 针对车辆姿态变化会引起飞轮电池安装基础运动的问题,利用子结构分析法,分别建立了7自由度车辆的动力学模型和5自由度飞轮电池转子的动力学模型,提出了将安装基础运动转化为对转子激励的动力学求解的方法,并分析了飞轮电池转子在路面输入引起安装基础振动变化情况下的振幅变化.结果表明,路面输入引起的安装基础振动改变了飞轮电池转子的受力,激励了飞轮电池转子在5个自由度上的振动. The pose change of a vehicle may result in the base motion of flywheel battery. In order to solve this problem, a 7-DOF （ Degree of Freedom） dynamic model of the vehicle and a 5-DOF dynamic model of the flywheel battery rotor are established via the substructure analysis method, and a method to transform the base motion into the dynamics of rotor excitation is proposed. Moreover, the vibration amplitude of the rotor which varies with the base vibration due to the pose change of vehicle, is analyzed. The results show that the base vibration due to the pose change results in the variation of the force which is exerted on the flywheel rotor and which excites the 5-DOF vibration of the rotor.
