摘要 以柔性铰为连接副建立了滚子链系统的SimMechanics多体动力学模型。模型考虑了完整的链轮齿廓。基于该模型,使用虚功原理及拉格朗日方法,得到了柔性铰的广义力及系统动力学方程。建立了完整的链轮齿廓下滚子与链轮的离散单元接触模型,引入接触对指示矩阵和接触局部坐标系,提出了基于齐次坐标变换的滚子与链轮接触的快速搜索策略。仿真得到了滚子与链轮的啮合过程中滚子与各段齿廓的接触碰撞力。通过与ADAMS仿真结果比较验证了该方法的正确性。 A multibody dynamic model of roller chain system was developed in SimMechanics by considering that components are interconnected by flexible joints, and sprockets have complete tooth profile. Based on this model, the generalized forces of the flexible joints and the dynamic equations of the system were obtained using the principle of virtual work and Lagrange methodology. Considering complete tooth profile, the distributed element contact model was established. By introducing contact- pairs index matrix and local contact coordinate systems, a fast method for contact search, which is based on homogeneous coordinate transformation, was presented. The contact-impact forces between roller and each element of tooth profile were achieved by simulation. The proposed method is validated by results comparison with ADAMS simulation.
