为对新型超高速包装机铝箔纸烟包推手装置的性能优化提供设计依据，研究了其运动特性。基于新型推手装置的解析模型，通过分析其工作原理，计算推手工作点的运动轨迹。采用多刚体动力学理论，建立该装置的仿真计算模型，求解推手工作点的运动轨迹。将运动轨迹的解析解与仿真解进行对比，二者一致性较好，验证了动力学仿真模型的正确性。应用推手装置仿真计算模型，对其位移、速度与加速度等关键运动参数进行分析，并对长臂推手进行加速度测试，将实验结果与仿真计算结果进行对比分析。结果表明：包装速度为1000包/min时，推手装置能够准确地实现预定的运动轨迹，平稳地将烟包推送到往复模盒中。

To provide a theoretical basis for optimizing its performance, the kinematic characteristics of foil-wrapped cigarettes pusher device in the new type ultrahigh-speed packer were studied. Based on the analytical model of the pusher, the movement trajectory of its working point was calculated by analyzing its working principle. By referring to the dynamics theory of multiple-rigid body, a simulation model was established for determining the movement trajectory of its working point. The trajectory obtained by the analytical model was compared with that by the simulation model, the two agreed pretty well, it confirmed the correctness of the dynamics simulation model. The key kinematic characteristics, including displacement, velocity and acceleration of the pusher were analyzed with the simulation model. The acceleration of long-arm pusher was tested and compared with the results of simulation calculation. It was proved that the pusher device could accurately moved along the preset trajectory and gently push foil-wrapped cigarettes into the reciprocating mandrel at the speed of 1 000 packet/min.
