Design and Optimization of Side Impact Beam of Car

Road safety is a very crucial concern nowadays. Many people die in road accidents every day. This research is based on previous researches on the side impact beam or intrusion beam of vehicle. The objective of this paper is to analyse and optimize the side impact beam based on resistance force and specific energy absorption during impact. Side impact causes more fatal injuries than front & rear impacts. And as we all know; passenger safety is the most important criteria while designing an automotive body. Side impact crashes can be fatal as there is no room for large deformation to protect the passenger from lateral impact. The side Door Intrusion Beam is one of the main energy-absorbing parts in event of a side impact. Till date, many types of research have been carried on side-impact & ways to reduce it. This paper begins with an overview of various cross-sections of the side impact beam, various materials, and their applications and importance. Also, we have done a simulation of a three-point bending test on a side impact beam with different combinations of material and cross-sections.
