Visual Analysis And Simulation Of Planar Linkage

In this paper,to improve the course teaching of mechanism theorem,a visual analysis and simulation program of planar linkage in three dimensional space has built up. Based on VC and OpenGL software platform,as a part of integrate planar mechanism analysis and simulation CAI,the mechanism theory has been adopted to analysis the movement trace and profile of linkage;adopt oriented object method to capsulate the class module. Each corresponding class module complete parameter storage and process;adopt message-map,message-trigger to organize the programming and response the user' s input;use the document-view structure of the visual VC++ MFC class foundation as the basis of the programming architecture to complete those functions. Use oriented object method to product the following class module:control class,render class,document class,mechanism class and other classes;adopt OpenGL library to draw the three dimensional graph based on the result of mechanism analysis;use model transforming,lighting,material,color,frame-buffer,display-list,graphics-component combine etc to draw the three-dimension mechanism and make the simulation of linkage has high reality.
