Virtual design and simulation in new produt development of automobile sunroof

In this paper the reverse engineering and Software Catia were applied to create the 3D digital model. Then the model was imported into ADAMS to build the virtual prototype. After that the key components which affect the movement characteristics of the sunroof were abstracted out to build the kinematic model. Then the virtual assembling, kinematics simulation and analysis were done with ADAMS software. Finally, a parameter optimization was done based on the study result of the simulation and analysis. The study in this paper can not only improve the design quality and development efficiency of new automotive sunroof productions, but also remarkably shorten the Production development period and reduce the development cost.
