| 摘 要： | 本文研究自动齿轮箱凸轮作动器的效率和磨损,着重于接触动力学。采用罚函数方法仿真凸轮和从动杆间接触,该模型基于有限元与连续弹性基础梁理论近似。采用Hertz理论考虑凸轮和从动杆间相对运动时主要曲率的变化计算基础模量。为比较接触力和不同凸轮轮廓的磨损,该模型仿真概括了整个档位。

| Abstract: | In this paper the efficiency and wear of the cam actuator of a robotized gearbox are investigated,focusing on contact dynamics. A penalty method is used to simulate contact between the cam and the follower. The model is based on a finite element approximation of the theory of beam on continuous elastic foundation. The foundation modulus is computer using Hertz theory taking into account the change of principal curvature during the relative motion between cam and follower. This model has been embodied in a c... |
