Research on the digitized models of automobile hubs based on computer simulation

Along with the rapid socio-economic and technological development, vehicles are widely used in China, especially in recent years, the rapid growing of automobile manufacturing industry which makes the automobile industry become a crucial pillar industry. A car wheel-hub is set as the research target according to the computer simulation theory, use the digital modeling software - Rhino as a platform, and then digitally analyze the wheel hubs. What´s more, using the characteristic of the digital curve to study of curve and surface, and using the generative principle of line and plane to establish the mathematics model of wheel hub, eventually concluded that can be applied in automobile hub of 3D digitizing model establishment method, which laid a foundation for digital research of other transportation hub.
