Abstract

The automotive crash box is a safety device installed at the front of vehicle which safeguard the vehicle component and passengers during the frontal collision. The crash box serves this function by deforming itself and absorbs the energy of collision. The crash box shape and size plays a vital role in deformation and energy absorption property. Considering the same shape and size nature of crash box the author proposed the performance evaluation of two different shape crash boxes mainly circular and hexagonal for improved passenger’s safety. In this study the CAD model is prepared and analyzed for deformation and energy absorbed. Later the same shape crash boxes are fabricated to study the behavior under loading experimentally for same parameters. The results obtained by analytical and experimental approach are compared and the optimum shape is proposed which has minimum deformation and maximum energy absorption property.
