摘要

针对贴标机传统凸轮机构存在的柔性冲击进行了分析

提出了一种新的凸轮机构设计方法。首先

介绍传统贴标机凸轮机构的运动要求和轨迹方程

提出其存在的问题;其次

在满足给定约束条件下

为实现凸轮机构从动件加速度曲线的各段角加速度尽可能趋小的多目标要求

采用多目标决策的线性加权法进行优化

并利用遗传算法设计求解凸轮机构从动件角速度曲线方程;再次

通过求解凸轮机构从动件的运动轨迹

对其进行修剪得到凸轮轮廓廓线;最后

由优化后的凸轮轮廓线设计加工出来凸轮机构

经装配试机运行后

证明新设计的凸轮机构减小了从动件的柔性冲击

具有一定的实际指导意义。

Abstract

The flexible impact of the conventional cam contour of the labeling machinery is analyzed

a new cam mechanism design method is proposed.Firstly

the movement condition and trajectory equation of the traditional cam mechanism are introduced

as well as the existence problems is pointed out.Secondly

under the given restrains

in order to realize multi-objective requirements of the follower segment angular acceleration of the acceleration curve is increasingly small as much as possible

the linear weighting method of multi-objective planning is used in the optimized analysis

the follower motion equation is redesigned by using the genetic algorithm.Once more

through solving the follower trajectory

then the cam contour is obtained by processing the trajectory.Finally

through after optimized cam profile

the cam mechanism is processed and the test running is carried out.The experimental results show that the cam mechanism of new design reduced the follower flexible impact

and it has a certain practical significance.
