摘　　要：对Jui-Pin Hung等人提出的碰撞法向速度公式的不足,提出了修正的碰撞法向速度公式。利用赫兹接触理论,建立了滚珠与反向器的接触碰撞力学模型;通过ADAMS仿真分析,验证了修正后的公式的可靠性;对比了滚珠与普通外插管和斜插管的碰撞区别;通过分析滚珠与斜插管的碰撞特点,设计了一种新型无管舌斜插管反向器。The collision normal velocity formula put forward by Jui-Pin Hung is revised. Using Hertz contact theory, the collision mechanics model between ball and return tube in the process of contact is established. By ADAMS simulation analysis, the reliability of the revised formula is verified. The balls with ordinary outside tube and oblique tube are compared. Through analyzing the characteristics of the ball and oblique tub, a new type of oblique tube without tongue is designed.
