摘　　要：运用三维建模软件Pro/E建立了滚珠丝杠副系统的零件装配模型,并通过ADAMS对建立的滚珠丝杠副仿真系统进行动力学仿真分析,绘制出滚珠间的碰撞力曲线图和滚珠线速度与自旋速度的变化数据表。结果表明:滚珠之间的碰撞在滚道内要比在反向过程内剧烈,且滚珠的自旋速度变化比滚珠线速度变化强度大。同时,验证了滚珠在滚道内的自旋速度和线速度变化确实比在反向过程中剧烈。仿真结果证实了所建仿真模型的有效性,为改善滚珠丝杠副性能,提高流畅性提供了技术支持。A model of ball screw assembly parts system was established by using three-dimensional modeling software Pro^E, and the dynamic simulation analysis of the ball screw pair simulation system was carried out by ADAMS. The force curve graph between the balls was drawed. The change table of line speed and the spin speed of the ball was drawed. The results show that the collision between balls is more intense than in the reverse process in the roller, and the spin speed changing of the ball is more intense than the dramatic changes in line speed. At the same time, it proves that the change of the spin speed and the linear speed of the ball in the rolling track is more severe than that in the reverse process. The simulation results confirm the validity of the simulation model, it can provide tech- nical support both to improve the performance of ball screw and to improve fluency.
