Modelling and optimization of car-to-car compatibility - Modellierung und optimierung von pkw-pkw-kompatibilität
conference paper
In this paper simple and more detailed MADYMO multibody models were used to simulate the car structure for improving the car-to-car compatibility of the whole car fleet. As a first step, survey studies were performed to develop a method for the optimization of car design with respect to frontal and side compatibility by means of the optimization module within MADYMO. As design parameters the stiffness and crush length of the cars were used. The object functions consisted of combinations of injury risk functions. The simple models gave good functions in the global response and proved the possibility of fleet optimizations by means of adapting the stiffness and size of specific parts of the front of the car. However, the translation of the overall properties to a specific car design is not straightforward. As a second step, more complex MADYMO multibody car models were developed that are representative for a certain car glass. Examples are given of the Chrysler Neon. In the future these detailed models should be applied in similar optimizations as were done in the first part of this study.
