摘　　要：针对DPH-260泡罩包装机夹持步进装置的PVC拉扯变形问题,基于Solidworks建模并利用ANSYS和ADAMS软件分别建立了改进前后夹持步进装置的虚拟样机及进行动力学仿真分析,得出PVC拉扯变形现象的原因并将改进前后仿真结果对比。针对改进后同步带传动机构传统动力学建模的局限性,将同步带离散为由Kelvin-Voigt单元柔性连接的质量块。最终对比了改进前后步进装置的运动曲线,通过理论分析建立了同步带传动机构动力学方程,为包装机步进装置的应用提供了理论参考。In view of the PVC pulling deformation problem of the clamping stepping device of DPH-260 blister packaging machine,based on Solidworks modeling,ANSYS and ADAMS software used,the virtual prototype of the improved front and rear clamping stepping device was established and the dynamic simulation was carried out.The reasons for the PVC pulling deformation phenomenon were obtained and the simulation results before and after the improvement were compared.Considering the limitation of traditional dynamic modeling of the improved synchronous belt transmission mechanism,the synchronous belt is discretized into mass blocks flexibly connected by Kelvin-Voigt element.Finally,the movement curves of the stepping device before and after the improvement were compared,and the dynamic equation of the synchronous belt transmission mechanism was established through theoretical analysis,which provided a theoretical reference for the application of the stepping device of the packaging machine.
