Impact Analysis of Bumper through Computational Design and Analysis Method

Politeknik Sultan Azlan Shah, Perak

Abstract

Bumper is one of the main parts which are used as a protection for the driver and passengers from the accidental impact due to front and rear low-speed crashes. In response to safety point of view, a bumper becomes an important part in preventing the impact force from being transferred to the passengers. In this paper, a domestic Proton Wira car bumper is being studied. The computer simulation method is used to study the impact analysis of front bumper. A modelling of front bumper is carried out by using CATIA. The bumper with the specific load and boundary conditions are analyzed using dynamic explicit analysis ABAQUS v6.6. A few parameters including material, design, and impact conditions are studied in a low velocity impact to analysis of front bumper by using a rigid block. The impact deformation, displacement and acceleration of the front bumper is being studied which can provide a reference for the next design and improvement.
