| 目的 针对药品包装封口机设计六杆机构，该机构输出构件滑块做直线运动，以完成直线封边作业。方法 根据封口直线机构处于极限位置时各杆长与角度之间的函数关系，运用ADAMS参数化建模功能计算出各角度初始值，在极限位置处建立其虚拟样机模型，并进行运动仿真及分析。结果 经过仿真分析得出，滑块行程为278 mm，速度最大值为1160 mm/s，加速度曲线斜率为0.7～0.9 s，在返程时不会影响封口的效果，封口直线机构运行平稳。结论 利用极限位置进行参数化建模，简单易行，适用于其他复杂机构的参数化建模。 |

| The work aims to design the six-bar mechanism for the medicine package sealing machine to enable the mechanism’s output component, the slider to make rectilinear motion, so as to complete linear edge sealing. According to the functional relationship between the bar length and the angle when the linear sealing mechanism was at the limit position, ADAMS parametric modeling function was used to calculate the initial values of each angle. The virtual prototype model was built at the limit position and the motion simulation and analysis were carried out. Based on the simulation analysis, the placement of slider was 278 mm, the maximum speed was 1160 mm/s, and the acceleration curve rate was 0.7~0.9 s. The sealing effects would not be affected because of the back tracking. The linear sealing mechanism ran smoothly. It is simple and feasible to establish parametric model through limit positions, and such method can be applied to the parametric modeling of other complex mechanisms. |
