Abstract

A crash box, an Impact Attenuator, is used as a safety device against crash by absorbing energy generated in the event of a collision and to provide safety to the driver from experiencing a sudden change in momentum. This is achieved by the device deforming plastically and it is installed in the forward most position (front bulkhead) of the car. This paper gives insight into the philosophy involved in making a self-designed crash box which meets the rule requirements set by FSAE. Firstly, the key concepts of crash box design are discussed, both theoretical and experimental. It also explains modeling of the crash box using CATIA V5, which enables to develop an FE model used for finite element analysis. Next, the steps involved in setting up of an FE model are detailed. This model is used to determine the average deceleration and peak deceleration offered to the vehicle during a collision. The model examines the failure of the bulkhead and bulkhead support structure of the vehicle. A finite element model thus developed enables the analysis of different crash box concepts. Finally, an experimental technique (Drop Test method) is presented to experimentally validate the energy absorbed by the crash box constructed
