Abstract
Abstract:
The goal of this paper is to present mathematical models to investigate and to optimize crash compatibility. Since a slight softer crumple zone is required for heavier vehicles to improve the compatibility, a smart structure is proposed to support the function of the existing vehicle and to optimize vehicle compatibility. The proposed structure consists of two fixed independently hydraulic cylinders besides the longitudinal members in parallel position. The models of both standard-standard and smart-standard vehicles in head-on collision are developed and are numerically solved. It is proven from simulations that the smart vehicle brings significantly improvement in vehicle compatibility. In addition, it is shown that the models can be used in an effective way to give a quick insight of real life crashes.
