Numerical and Experimental Analysis of Energy Absorption of Aluminium Honey Comb Filledp IPE for Car Bumper Application - A Review

In general car bumper is considered as the front most and rear most part designed to withstand damage to vehicle’s safety systems. During frontal crash, the bumper beam is the main component which undergoes damage and transfers remaining energy to other parts of the car. Thus, there is a need to further improve the design of bumper beam to ensure the safety of automobile confirming minimum accelerations are transferred to the occupants. In this work an attempt is made to further improve the material of the bumper beam to enhance the passive safety of the occupants. This is proposed to achieve by using aluminium honey-comb panel as a filler material between bumper beam and support region. Primarily the behavior of the hollow rectangular aluminium tubes will be determined using Ansys. The honey comb panel will be embedded into the hollow rectangular aluminium tube which will be arranged along the bumper space so that tubes can withstand major portion of the impact energy. Enough space between the tubes will be provided to permit displacement to tubes during crush. The influence of aluminium honey comb panels will be analyzed.
