Impact analysis of bumper beam to be proposed for Indian passenger cars

Abstract

Cars equipped with modern devices like rare parking sensor, parking camera, etc. helps in avoiding low-speed impact. However, in reality, these low-speed impacts are still happening very frequently because of no of factors like slow-moving heavy traffic, the experience of the driver during parking the vehicle, etc. The bumpers, which essentially act as low-speed energy absorbers, are provided inthe rear and front side of a vehicle. In the present work, three different bumper beamsare fabricated based on the design parameters obtained during numerical simulation conducted as per low-speed impact guideline of standards of automotive stated in E.C.E. United Nations Agreement, Regulation no. 42 (1994). Theenergy absorption capacity and strength of these bumper beams arenumerically investigated. The numerical simulations are obtained for low-speed pendulum impact test to prove the crashworthiness of the proposed bumper beams.
