Virtual Manufacturing Technology is new development direction to traditional CAD/CAM technology. At present, VMT becomes the important aided tool of modern mechanical engineering design. Virtual simulation is the firm basis of realizing such technology. VRML is a 3D modeling language and popular data transmission choice on the Internet. This paper researches structural parameter design and simulation of 2-DOF Parallel Mechanism. 3D modeling methods by UG software and the mechanism testing platform module were presented and given. And then mechanism’s motion equations were deduced. This paper provides a simulation system of 2-DOF Parallel Mechanism testing platform on the basis of its movement analysis, and also offers methods and procedure of developing the interactive simulation. At last, the interactive simulation can be observed and the solution validity is verified.
