Kinematic Simulation of Machine Par ts Based on VRML

Through introducing briefly the definition,characteristic of virtual reality modeling language(VRML) and the design procedure in the course of virtual product design,it proves that visual reality(VR) technology is not only feasible in the virtual product design,but also gets good results.On the basis of this,through a virtual product design instance,how to use VRML to realize the kinematic simulation of the virtual products was explained in detail.First of all,solid models through the three-dimensional model software was set up and exported with DXF file.Through VRML output interface provided by tool software such as 3DS MAX,WRL file was generated.Then WRL file was edited in order to realize the kinematic simulation effects of machine parts.Thus,it is helpful to learn the structure of the mechanical part,solid shape and movement characteristic.
