| Abstract: | Auto body, as one of the four auto assemblies, always is the difficult one in the design and manufacture of a vehicle due to the complexity and particularity of its shape and structure. Using the combination of three-dimensional software and reverse modeling method to design and optimize auto body can greatly reduce the automobile design and manufacturing cycle. Firstly, the reverse modeling technology of a auto body is studied. Secondly, surface cloud data of a car made in China are measured and obtained using an optical scanner. Then, the measured data are processed using Geomagic software, and the auto body surface is reconstructed based on NURBS surface modeling. Finally, the surface modeling and analysis of auto body are conducted in software UG. The research is prepared for the subsequent structure optimization design of the auto body. |
