摘　　要：为了提高电池包装机的包装效率、减振降噪、提高电池包装质量,建立凸轮送料机构的虚拟样机模型并基于Adams分析软件进行机构的动力学仿真,基于动力学曲线特性的分析对凸轮廓线进行改进设计并进一步探讨了弹簧参数对机构的影响,找到最优的弹簧刚度及预紧力。仿真及试验结果表明:改进后的凸轮送料机构动力学特性明显变好;凸轮廓线和弹簧参数是影响凸轮机构运行稳定性的重要因素,当从动摆杆采用五次多项式运动规律,弹簧刚度为0.2 N/mm,预紧力为15 N时,机构稳定性最好,整机噪音明显降低,对提高电池包装质量和延长机器的使用寿命具有重要意义。In order to improve the packaging efficiency of battery packaging machine,reduce vibration and noise,and improve the quality of battery packaging,this paper established a virtual prototype model of the cam feeding mechanism and performed dynamic simulation of the mechanism based on ADAMS software.Based on the analysis of the dynamic curve characteristics,the cam profile was improved and the influence of the spring parameters on the mechanism is further explored to find the optimal spring stiffness and preload.The simulation and test results show that the dynamic characteristics of the improved cam feeding mechanism are obviously improved.The cam profile and spring parameters are important factors affecting the running stability of the cam mechanism.When the driven pendulum adopts the fifth-order polynomial motion law,the spring stiffness is0.2 N/mm and the pre-tightening force is 15 N,the mechanism has the best stability and the noise is significantly reduced,which is of great significance for improving battery packaging quality and prolonging machine life.
