Modeling method of vehicle body in white based on implicit parametrization

As to the fact that lots of manpower and time are spent for conceptual design of new vehicle type in traditional method,by which many CAD models and CAE models need to be established for a large number of programs to be selected,the basic and advanced elements and the techniques of multilayer plane modeling and mapping link in implicit parametrization modeling of vehicle body are introduced,and the vehicle body modeling ideas based on implicit parametrization are briefed;the front of the body in white is modeled for a vehicle;the crash simulations based on the parametrization model and the original finite element model are analyzed and compared,and the results indicate that it is feasible to use the implicit parametrization modeling method to perform conceptual vehicle development,which can implement the rapid evaluation on vehicle structure performance in early development.
