摘　　要：为了解大型废钢破碎机转子在碰撞过程中的力学特性,以及在相关力学情况下的零部件优化设计的可能性,通过虚拟样机技术对特定型号的废钢破碎机转子进行了碰撞过程的仿真分析,并且得到了碰撞过程中的最大接触力;同时结合ANSYS软件对废钢破碎机转子的主要受力件进行了有限元分析,得到锤头和销轴这两个主要受力件的应力云图。结合强度校核可知,该型破碎机转子中的主要受力部件的尺寸及结构还存在一定的优化空间。In order to understand the mechanical properties of the rotor of the large-scale steel scrap crusher during the rotor collision process and the design optimization possibility of mechanical parts,the paper applied virtual prototype technology to simulate the rotor of a specific steel scrap crusher during the rotor collision process,and obtained the maximum contact force during collision process. Meanwhile,ANSYS was combined to conduct FEA on main stress parts of the rotor,and the stress contours of two main stress parts of the hammerhead and the pin shaft were obtained. Strength verification results showed that the dimension and the structure of main stress parts of the rotor possessed some optimization space.
