提出一种曲轴滚磨光整加工工艺。将离散元法应用于曲轴滚磨光整加工分析，通过三维EDEM软件建立曲轴滚磨光整加工动态模型，对料箱内磨料颗粒系统的运动过程进行可视化仿真。通过分析加工过程中磨料颗粒的位置、速度以及磨料颗粒对曲轴的接触力，探讨同一周期内不同位置磨料颗粒系统速度场分布对加工效果的影响，分析磨料颗粒系统平均速度随加工时间变化的规律，研究磨料颗粒系统与曲轴之间的平均接触力，这对于提高曲轴滚磨光整加工技术具有积极的意义。%Now,crankshaft barrel finishing technology has been well used ,but study only focused on process experiments ,and knowledge of its micro machining mechanism is insufficient ,which has become the developing bottleneck of crankshaft barrel fin-ishing technology.For this reason,the discrete element method is applied to analyse the crankshaft barrel finishing .In order to visually simulate the movement process of particle system inside the workbin ,crankshaft barrel finishing dynamic model is built by using three-dimensional software EDEM .By analyzing particle position ,velocity in the processing and particle contact force of the crankshaft,the relation between different locations particle velocity distribution within the same cycle systems and the processing effect is discussed ,the law that average speed of particle system changes with the processing time is analyzed ,and contact force between particle system and crankshaft is studied ,which should be of great significance for the further development and industrial applications of crankshaft barrel finishing .
