Structural Optimization of Automobile Bumper Using Honeycomb Structure

Bumpers are the primary parts in any vehicle and are used to absorb the crash energy for safety of passengers and minimise the damage of other components. Now a days automobile manufacturing industries are focusing on minimizing the cost of manufacturing and weight of the vehicle by decreasing the material usage and machining cost. In this process vehicles are failing in safety standards and even for a minor dents service became costly. So in this paper, honeycomb structured fascia is used as the bumper base and then the performance of bumper is studied by varying the honeycomb cell dimensions. These testing were done according to the RCAR safety standards (i. e. , 2.6m/s full frontal& 1.3m/s corner impact) and simulated by using ANSYS Workbench.
