Title: A PARAMETRIC EVALUATION OF VEHICLE CRASH PERFORMANCE. SAE INTERNATIONAL CONGRESS AND EXPOSITION, SP-807, FEBRUARY 26-MARCH 2, 1990, DETROIT, MICHIGAN
Abstract: This paper describes the behavior of a driver-side occupant restrained by an airbag system in a passenger vehicle at a frontal barrier crash. In order to secure effective occupant protection at collisions, it is necessary to examine closely steering system movements due to the rearward movement of the dashboard as well as vehicle deformation characteristics. Generally this is for vehicles with a small frontal crash space. The authors examine the influence of these two parameters on occupant injury indices using the MADYMO 2D computer simulation program. As a result it has been found that it is important to model the axial collapse and the rotation of the steering system in the vertical plane caused by dashboard deformation, in order to achieve good correlations between an experiment and a simulation. It is demonstrated that the parametric study clarifies the influence of the vehicle deformation characteristics which is represented by a combination of two simplified trapezoids, as well as of the movement of the steering system, on effective occupant protection for an exampled vehicle. The results of the simulation are validated by the full scale vehicle crash test.
