Research on Virtual Designing System of Cam Mechanisms Based on MATLAB and VRML

Integrating Matlab Virtual Reality Toolbox,Matlab language and VRML technology,a virtual design system has been developed,on which various cam mechanisms can be designed.The software has a simple and clear graphical user interfaces,and can provide user with parameterized design,three-dimensional graphics and virtual simulation.Further more,the software has some assistant function such as parameter optimization,movement performance analysis,output for graphics and character data,and so on.On this system,user can interact on the virtual scene of cam mechanism created Real-timely,and control the course of simulation.The system indicates that the method can effectively reduce the difficulties and workload,and shorten the time of programing accordingly,because it could take advantage of MATLAB's and VRML's strongpoints.
