利用 ADAMS 分析软件,对酒瓶装箱机构的建模仿真、优化进行了分析和探讨。 在此基础上,基于间隙矢量模型,建立了考虑铰接处两构件由于制造和装配误差引起的间隙运动副模型,描述了间隙运动副两构件间的相对运动关系和基于非线性碰撞接触模式的动力学约束关系,分析了运动副间隙对系统运动学及动力学特性的影响。 结果表明利用 ADAMS 进行仿真,是研究含间隙运动副机构的一种有效方法,可为多体机构设计及动力学行为描述提供精确预测,对其他含间隙运动副机构的动力学研究具有普遍意义。

Model of wine bottle packaging mechanism was established and optimization was carried out based on ADAMS. Motion pair model of linkage with clearance caused by manufacturing and assembling error was established based on clearance vector model. The kinetic relationship between two linked bodies was obtained, and the dynamic relationship based on the model of nonlinear contact force was also presented. The influence of clearance of motion pair on kinetic and dynamic characteristics of the system was analyzed. The result showed that ADAMS simulation is a kind of effective method to study motion pair with clearance, which can provide accurate prediction for design and dynamic description of multi body mechanism; It has universal significance for analysis of other mechanism with clearance.
