平面盘形凸轮轮廓曲线统一建模的研究

摘要

将从动件的直线往复移动和定点往复摆动用虚拟摆动统一表示,采用单参数包络曲线理论建立直动和摆动从动件平面盘形凸轮轮廓的统一数学表达式。根据统一的数学表达式可以开发出一套适合于各类平面盘形凸轮机构的CAD软件包。%In this article,the unified profile expression of the planar cam mechanism with translation or oscillation follower is established based on the theory of envelopes for 1 parameter family of curves.According to the unified profile expression,the CAD system of cam for all kinds of planar cam mechanism can be developed.
