In the standards about the contour dimension of automobile in most countries, the height difference of body symmetrical points or body inclination angle of automobile was specified. To improve the vehicle performance and operation safety, a measurement method of car body inclination angle was studied. According to the camera calibration and the distance between camera and automobile, the front ...

In the process of car body design, various surfaces can be generated,from the given boundary curves. Depending tqon the method qf the surface generation and the qualip qf the boundary curves provided, the resulting surfaces may have global 07” local irregularities in many cases. Thus it would be necessarvfor the designer to evaluate the surface quality and to rnodifi the surface or to use the d...

Abstract With the rapid development of computer technology in recent years, this paper explores feasibility applying computational fluid dynamics (CFD) to study external flow-field automobile body. The numerical solution provides pressure and velocity distribution car body, such as aerodynamic field field, order obtain information resistance, lift, lateral force related torque, which can be fur...

With the developments in automobile technologies; more focus is given to the vehicle weight reduction. About 30% weight is contributed by the automobile body. Now-a-days, plastic composites are used to manufacture automobile bodies as they are strong, light, corrosion resistant and easy to use. This paper represents the selection of plastic composites to build vehicle roof as a replacement of c...
