摘　　要：为满足印刷机械对递纸机构高速平稳运行的要求,采用共轭凸轮和摇杆滑块构成递纸机构,本文以高速递纸机构为对象,研究能耗最优的动力学优化设计.首先,根据递纸作业要求选定凸轮从动件运动规律,建立机构运动学模型,通过计算确定共轭凸轮轮廓.在此基础上,利用牛顿欧拉法建立机构的动力学模型,求出驱动力矩、驱动功率以及运动周期内的能耗.最后,以能耗最小为目标,采用粒子群优化算法对递纸机构进行动力学优化设计.实例证明,优化后的递纸机构节能效果明显.In order to meet requirements of feeding paper stably in high-speed operation, the paper-feeding mechanism usually consists of a conjugate cam and a rocker slider. The dynamic optimization of high paper-feeding mechanism based on minimum energy consumption is presented in this paper. Firstly, the cam follower＇ s movement rule is obtained and the conjugate cam＇ s contour coordinates are presented through the kinematics analysis. Then, the dynamic model of the mechanism is formulated by Newton-Euler method. The driving torque, power and energy consumption of motion period are obtained. Finally, PSO is used in the dynamic optimization design of this mechanism, taking the minimum energy consumption as objective function. A specific example proves that the optimized paper- feeding mechanism is energy efficient.
