【摘要】：目的基于ADAMS软件,对包装机推料机构进行虚拟样机建模。方法对机构进行仿真,在此基础上建立铰链间隙模型、柔性体模型和铰链间隙柔性体都存在的模型。通过与理想模型运动曲线进行对比,分析各个铰链间隙和连杆柔性对运动学规律的影响。结果运动副间隙(0.25 cm)对推料板的速度、加速度影响明显,会产生振荡现象;同时考虑运动副间隙(0.25 cm)和构件柔性,得到的速度、加速度曲线趋于平稳,缓解了铰链间隙产生的冲击。结论适当考虑连杆柔性,可以缓解铰链间隙产生的振荡,使推料板运动趋于稳定。
[Abstract]:Aim based on ADAMS software, the virtual prototyping model of the push mechanism of the packaging machine was established, and the hinge clearance model was established based on the simulation of the mechanism. By comparing with the ideal model, the effects of hinge clearance and linkage flexibility on kinematics are analyzed. The results show that the clearance of motion pair is 0.25 cm) and the velocity of push plate is about 0.25 cm, and the results are as follows: (1) the model of flexible body and the flexible body with hinge clearance are compared with the ideal model, and the effects of hinge clearance and linkage flexibility on kinematics are analyzed. The acceleration effect is obvious and the oscillation will occur, and the velocity and acceleration curve obtained by considering the clearance of motion pair (0.25 cm) and the flexibility of the component tend to be stable, which alleviates the impact caused by the hinge clearance. Conclusion the flexibility of connecting rod is considered appropriately. The oscillations produced by hinge clearance can be alleviated, and the movement of the pushing plate tends to be stable.
