摘　　要：滚子摆动从动件盘形凸轮机构稳态运行时的负载转矩波动幅度较大,在高速高精度的自动化设备中,负载波动幅度影响伺服电机性能。针对其负载特点,提出了一种通过优化主动件和从动件作用过程中的阻力矩,进而降低机构整体负载转矩波动幅度的优化方法。该方法是基于凸轮曲线运动规律调制处理方法及粒子群算法,通过生成新的凸轮廓线来完成优化过程。将此方法应用到某高速包装机的交接鼓轮中,完成了装置的优化。仿真结果表明,该方法可以有效地减小装置负载波动幅度。The large load torque fluctuation of disc cam mechanism with oscillating roller followers mainly affects the steady performance of servo motor in high-speed precision machinery.According to the load characteristic,a optimization method for reducing the mechanism overall load torque fluctuation is proposed by optimizing the resistance torque in the process of active parts and follower.This method is based on the cam curve motion law modulation method and particle swarm optimization algorithm,through generating new cam profile to complete the optimization process.The optimization of device is completed by applying this method on transfer mechanism in high speed packaging machinery.The simulation result shows that,the load fluctuation of device can be effectively reduceds.
