Abstract


For domestic currently does not have study on the parametric of electric automobile body modeling design which is put forward in this paper . And the paper present give the parametric of electric automobile body modeling design method. The method is based on the parameters of the whole electric car accord with the body modeling design, and it can effectively improve the range of electric cars. This paper firstly introduced the basic structure of the electric vehicles and the constitute elements of the electric vehicles , and analyzed the technological factors which affected the shape of the body . And then the paper focused on body shape parameters to improve the driving range and the relations between them ,which is as a guidance for instance electric vehicle styling design and parameter settings and optimization.Secondly , because of technical factor influenced the body shape , the paper made the major parts selection and set the basic parameters of the electric vehicle . And then the paper used CFD and CAD to improve the parameters of the electric vehicle . The paper use the new software avl-fire to simulate the aerodynamic of the electric vehicle , and made a example to verify the reliability of the new software.At last, the paper use Rhino and Vray to give realistic scene of electric automobile body shape . And the paper use the constant velocity method to illustrate the result is superior .The research of the paper to explore an effective way for domestic design of the parametric of electric automobile body modeling, and has made important contributions to the promotion of the range of electric cars.
