The theoretic contour line and actual contour line of compensatory cam was ascertained with " reversal method " 利用“反转法” ,确定了补偿凸轮的理论廓线及实际廓线。
So we can complete the kinematic analysis of the cam mechanism by the analysis of the corresponding assur - group . based on the method , this paper deals with plannar disc - cam mechanisms with different types of followers . the main points of this paper are as follows 基于杆组的分析方法,本文围绕各种类型从动件的平面盘形凸轮机构做了如下工作: 1 .根据凸轮机构的检测数据利用三次周期样条函数插值法对凸轮实际廓线进行曲线拟合。
In the paper , based on the method of low pair replacing with high pair , the problem of cam design was transferred to that of linkage design . by means of rotary unit vectors , the equations of displacement , velocity and acceleration of the replacement mechanisms were developed . and then , the virtual linkage ' s length and direction were deduced 论文基于高副低代原理,将平面凸轮机构设计与再现函数的平面连杆机构设计统一为同一种方法,运用圆向量函数建立代换机构的位移、速度、加速度矢量方程式,求取虚拟连杆杆长和方向,由此展开凸轮理论廓线、实际廓线、曲率半径和压力角的求解,并得出用圆形刀具加工凸轮时刀具中心的轨迹方程。
Some examples are given in this dissertation . first , the coordinate values of a group of discrete points on the cam profile are achieved by conventional design method which are then used as measured data of the cam profile . then the kinematic analysis of the cam mechanism is performed by the method developed in this paper 本文以已知从动件运动规律的凸轮机构为例,利用正设计方法求出凸轮实际廓线一组离散点坐标值,并以此作为凸轮检测数据,运用本文提出的分析方法进行运动反求,并将反求所得结果与理论结果加以分析比较。
On the basis of the known actual contour equation of cam in the disk typed cam mechanism with swinging oblique bottomed follower , this paper expounded another method for determining inversely the track equation of cutter center and the motion law of follower , and three key techniques in numerical inverse seeking were solved successfully by adopting the method of curve matching 摘要根据已知摆动斜底从动件盘状凸轮机构的凸轮实际廓线方程,阐述了反求确定刀具中心轨迹方程和从动件运动规律的另一种方法,并采用曲线拟合等方法成功地解决了数值反求中的3个关键技术。
