摘　　要：建立 45 0t行星传动起升机构事故模型 ,分析从断电开始飞车发生过程中电动机和重物的运动参数 ,达到飞车的时间为 2 .78s,电动机的角加速度主要取决于物品重量和电动机轴上的转动惯量。Built up the fault model of the electro-motors burst up in 450 t hoisting mechanism with planetary gear reducer, analyzed the kinematical parameters of the object been lifted and the electro-motors in course of the accident since the electricity were broken, from which to the moment the electro-motors burst up It is 2.78 s. The angle acceleration of the rotors in the electro-motors depends upon the load and the moment of inertia on the electromotor axis principally.
