Crash box is a separate component in vehicle which is mounted in between main frame of the car and front bumper. At the time of the accident it deforms axially and absorbs accidental energy. Crash box structure provides comfort to the passenger at the time of impact. It works as safe guard for the costly components behind the bumper like engine hood and cooling system. In this report plane crash box geometry is studied for the energy absorption. Study is based on analytical, experimental and numerical work. Various parameters like width, thickness, filler material which affects the crash box performance are studied by using Design of experiments. In this experiment we will be using ABAQUS CAE as a modelling and analysis software.
