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. Various parameters like width, thickness, filler material which affects the crash box performance are studied by using Design of experiments explicit dynamic analysis of different shape Crash box in ANSYS workbench.
