Abstract: 　    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 no t o nly feasible in the virtual product desig n, but also ge ts good results.On the basis of this, throug h a virtual pro duct design instance , how to use VRM L to realize the kinematic simulation of the virtual products w as explained in detail .First of all , solid models throug h the three - dimensional model softw are was set up and ex ported with DXF file .Throug h VRML output interface provided by tool software such as 3DS MAX, WRL file was generated .Then WRL file w as edited in order to realize the kinematic simulation effects of machine parts.Thus, it is helpful to learn the structure of the mechanical par t , solid shape and movement characteristic .
