| 摘 要： | 将混合驱动理论应用于凸轮连杆机构,介绍了混合驱动凸轮连杆机构的概念和意义.在对其进行了运动学分析的基础上,使用图解法推导出混合驱动凸轮连杆机构柔性空间边界条件.指出混合驱动凸轮连杆机构再现轨迹应满足柔性空间边界条件和运动学几何约束条件.设计了实现成组超椭圆轨迹的凸轮连杆机构实例.仿真实例结果表明,混合驱动凸轮连杆机构可以在比较规范的柔性空间内精确实现复杂的相同运动规律或不同运动规律的成组轨迹.

| Abstract: | The theory of the hybrid mechanism are applied in the research of the cam-linkage.The conception and signification of hybrid cam-linkage mechanism are introduced.Based on the kinematics analysis,the condition of the flexible workspace boundary of hybrid cam-linkage mechanism is analyzed by using the graphic method.It indicates that hybrid cam-linkage should satisfy the conditions of the flexible workspace boundary and kinetic dimension restriction for regenerating trajectory.The example of realizing super-ellipse multiple trajectories is designed.Simulation results show that hybrid cam-linkage mechanism can generate multiple complicated trajectories with the same laws or the different laws in the specification flexible workspace. |
