Considering the narrow space between the bumper and the outside skin, the filling foam can't be satisfied with the high standard requirements of pedestrian protection regulations. A scheme is proposed in this paper that using an energy absorption panel (EAP) to replaces the filling foam. Firstly, an impact model of collision between the car and a lower leg is built according to Euro NCAP regulations...
This paper is concerned with crashworthiness design of a front rail on a vehicle chassis frame structure considering crash direction uncertainty. Front rail as a main energy absorption component in front impact, may perform low energy-absorption deformation in front angle impact, such as global bending collapse. Magic Cube approach (MQ), a systematic design approach, is conducted to analyze the design...
In general, car body parts are very complex models by thousands of differential geometrically operations. For the computer-aided car-body part automatic modeling system, this complexity is a big challenge. This paper proposes a new body-based modeling method, using body-based features and a "sculpturing" strategy to create complex model via a computer car-body parts design system. This method...
Aiming at the problem of sheet metal sheared edge fracture appearing before deformation reaches its normal deformation capacity, the mechanism of stamping edge deformation capacity decreasing was studied through analyzing microstruction of sheared edge. Based on stress and strain states of sheared tensile being as the same as that of simple tensile test, propose a modified simple tensile test to research...
Two kinds of experimental dies containing class "A" surface feature of auto body outer panel are designed and manufactured in order to emerge the surface wrinkle of auto body panel. By doing stamping experiment in the dies, the wrinkling phenomenon is observed. At the same time, numerical simulation based on an independently developed commercial CAE software KMAS/UFT of sheet metal forming...
The application of case libraries has become a main problem in engineering designs. This paper presents an organizing scheme structured in catalogs and archives to design auto-body panel die-design case library. Meanwhile, we have developed a case library framework based on grid, and solved the principal problems existing in current case libraries. For example, the applications are restricted to small...
