| 摘 要： | 共轭运动是机械加工和机械传动中一种最普遍的运动形式。本文讨论了作典型共轭运动的刚体的动力学问题。在讨论中,用向量的回转来描述刚体的定点转动,而描述一般刚体运动的Lagrange坐标取为质心位置向量、刚体瞬时回转轴线以及绕该回转轴线回转的角度,使共轭运动系统的动力学问题的列式变得简单。

| Abstract: | Conjugate motion is the type of motion most commonly employed in mechanical processing and mechanical drive chains.This paper studies the dynamic problem of systems with typical conjugate motions. Vector rotation is applied to describe the fixed-point rotation. The Lagrangian generalized coordinates, describing the general motion of a body in three-dimensional space,are chosen, the position vector of its mass center, the instantaneous rotation axis and the rotation angle arcund that axis. This renders the formulation of the dynamic problem of a conjugate motion system much easier and more practical. |
