摘　　要：在分析立轴冲击式破碎机结构和工作原理的基础上，进行了转子的Solid Works三维建模．通过将模型导入ADAMS中进行动力学仿真，模拟破碎机在运转中物料的抛出过程，得到了转子所受最大冲击力和平均冲击力随转速的不同变化，说明降低最大冲击力的值和频率既需要考虑转子结构及相关参数的优化，还要分析进料粒度均匀性的影响．仿真结果表明，转速是影响立轴冲击破碎机破碎质量和效率的重要因素，破碎效果不总是随着转速的提高而提高；1450～1750r／min是转子受力均衡，能获得平稳运转的转速区间；降低最大冲击力的值和频率既要考虑转子结构及相关参数的优化，还要分析进料粒度均匀性的影响．Based on the analysis of the structure and the working principles of the vertical shaft impact crusher, set up the three-dimensional modeling of the rotor in Solid Works. Through the importation of the 3 D model into AD-AMS for the dynamic simulation, simulated the throwing process of the materials when the crusher was in operation, then gotten the variation of the biggest and average impact force suffered by the rotor in different spindle speeds. Thus, reducing the value of the biggest impact and frequency need to consider both the structure of the rotor and the optimization of the related parameters and the impact of the feed particles uniformality. Simulation results show that the speed of the rotor is an important factor that impacts the crushing quality and efficiency of the vertical shaft impact crusher, but the crushing effect is not always rising with the speed increasing. 1 450 - 1 750 r/min is the speed range of the rotor, between which the rotor suffers balanced force and can gain stable operation. In addition, on reducing the value and frequency of the greatest impact, for one thing, the rotor structure and the optimization of the relevant parameters need to be taken into consideration, for another, the impact of the uniformity of the feed particle size should also be analyzed.
