| 目的 基于ADAMS二次开发，为包装机械中一类常用凸轮连杆系统开发专用的凸轮轮廓CAD系统，使用ADAMS为凸轮外形轮廓对系统动态稳定性的影响提供一种直观的评估方法。方法 依据凸轮连杆系统的结构特点，使用ADAMS命令语言完成CAD系统的开发。将凸轮连杆长摆臂系统作为研究对象，通过ADAMS刚柔耦合仿真分析，对比正弦和改进正弦2种不同加速度运动规律设计的凸轮在高速运行时执行构件的动态稳定性相关指标，从而验证刚柔耦合仿真分析应用于凸轮连杆系统的正确性。结果 使用改进正弦加速度运动规律设计的凸轮，系统执行末端的实际最大速度、最大加速度、实际位移曲线最大波动量等动态稳定性评价指标更优异，符合理论分析。结论 ADAMS刚柔耦合仿真结果能正确反映凸轮轮廓对系统动态稳定性的影响，该分析方法有助于设计出更合理的凸轮轮廓。 |

| The work aims to develop a dedicated cam profile CAD system for a common type of cam linkage system in packaging machinery based on the secondary development of ADAMS. ADAMS was used to provide an intuitive assessment method for the influence of cam profile on the dynamic stability of the system. According to the structural characteristics of the cam linkage system, the ADAMS command language was used to complete the development of CAD system. With the long swing arm of cam linkage system as the research object, through the ADAMS rigid-flexible coupling simulation analysis, the related indicators of dynamic stability of the actuating members were compared when the cam designed based on different acceleration motion laws of the sine and the modified sine was running at high speeds, thus verifying the correctness of rigid-flexible coupling simulation analysis applied to the cam linkage system. The actual maximum speed, the maximum acceleration, the maximum fluctuation of the actual displacement curve and other evaluation indicators of dynamic stability were better when the cam designed based on the modified sine acceleration motion law was applied, which was in line with the theoretical analysis. ADAMS rigid-flexible coupling simulation results can correctly reflect the influence of cam profile on the dynamic stability of the system. This analysis method helps to design a more rational cam profile. |
