摘　　要：分析了立式行星磨的结构特性，利用牛顿定理建立了系统的动力学方程。采用线性关系表示异步电动机启动阶段转速与时间的关系，计算出立式行星磨的启动时间范围为7．94—10．32s。采用多体动力学软件ADAMS模拟了立式行星磨启动阶段的动态行为，建议实际操作时以适当的软启动方式启动，开车10s后加入物料并使加料均匀。The kinetic equation of vertical planetary mill is established using the Newtong Law based on the analysis of its structural characteristics. The start-up time of the mill is calculated to be 7.94 - 10.32 s by a linear formulation for the rotating velocity-time relationship to be 7.94 - 10.32 s. The dynamic behavior of vertical planetary mill in the start stage is simulated by multi-body dynamics simulation software ADAMS. It is suggested that the mill be started by soft mode and the material be fed uniformly 10s after the start.
