Abstract

<jats:title>Abstract</jats:title><jats:p>Bumper is one of the essential parts in an automobile. During collision, bumper is used as a protection shield to safeguard passengers and the body of the vehicle. We know that, death in accident is very common not only in India but also all over the world. Therefore, safety of passengers and automobile body must be considered as primary criteria at the time of vehicle design. ABS is a material which has high impact strength which is used for manufacturing automobile bumper. In this research, we endeavour to analyse three different front bumpers of expensive cars which are highly competitive in the automobile market. CATIA V5R21 is the software used for modelling the bumpers and ANSYS 19.2 is used for analysing each bumper with appropriate velocities. In this research, thickness of all the bumpers is considered as 5 mm and the concrete wall where it is collided to make impact collision is of thickness 10 mm. By using explicit dynamic condition with exact boundary conditions, we determine the best or optimistic design by comparing the results of various factors such as equivalent stress, total deformation, directional deformation and equivalent plastic strain.</jats:p>
