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。
The work aims to build a virtual prototype model of pusher for packaging machine based on ADAMS. The simulation of pusher was carried out, based on which the hinge gap model, the flexible body model and the hinge gap flexible body model were established. Through the comparison with the motion curves of ideal model, the influences of each hinge gap and linkage flexibility on the kinematics law were analyzed. The effect of kinematic pair clearance（0.25 cm） on speed and acceleration of pushing plate was obvious, which caused oscillation; meanwhile, kinematic pair clearance（0.25 cm） and component flexibility were considered. The speed and acceleration curves obtained tended to be stable, which eased the hinge gap impact. Appropriate considerations taken for linkage flexibility can ease the oscillation generated by hinge gap, so as to enable the pushing plate to move stably.
