基于刚柔耦合模型的卡扣机构动力学仿真分析

摘要

The paper establishes a snap-in mechanism rigid coupling model by the ADAMS,which is used to accurately and truly reflect the movement of the snap-in mechanism and analyzes the dynamics and multi-body model of the lifts and the snap-in mechanism.Through the analysis,it is found that significant fluctuation exists in the velocity and acceleration curves,when the displacement curve of the rigid coupling model remains unchanged and its reason is analyzed.The guiding direction is provided for further optimizing the mechanism.%运用ADAMS建立了卡扣机构刚柔耦合模型,准确并真实地反应出了卡扣机构的运动情况,将升降台和卡扣机构动力学特性与多刚体模型进行对比分析.通过分析发现,基于刚柔耦合模型下升降台和卡扣机构在位移曲线保持不变的情况下,工作时的速度、加速度曲线有明显波动,并通过分析波动的原因,为机构的进一步优化提出了指导方向.
