基于Matlab的共轭凸轮机构设计

The Matlab-Based Development of Conjugate Cam Design

以满足机构许用压力角为约束条件,利用Matlab开发了一款共轭凸轮辅助设计软件,可视化求解共轭凸轮转动中心的可行域,通过人机交互在可行域内选定凸轮转动中心位置,自动生成主、副凸轮的廓线及其特征点数据,极大提高了共轭凸轮的设计效率.Matlab软件生成的数据文件可直接用于数控加工,具有重要的实际应用价值.

To meet the requirement of allowed pressure angle,a conjugate cam computer-aided design software is developed based on Matlab which calculates the feasible region for the location of cam shaft visually.The software can generate the main and vice cams profile curves and its characteristic point data automatically after user picks the location of cam shaft from the feasible region through humancomputer interaction,which helps to improve the efficiency substantially of conjugate cams design.Data files generated from Matlab software can be directly used in computer numerical control machining,so it also has an important practical applications value.
