AIRBAG PERFORMANCE SIMULATION USING FINITE ELEMENT AND IMPACT BIOMECHANICS METHODS FOR HUMAN INJURY PREVENTION DURING ACCIDENT OF VEHICLES

ABSTRACT Several people die every year due to vehicle accidents. The main aim of this study is evaluate the performance of airbag using Finite Element Methods (FEM). As FEM is a very advance tool to analyze stress-strain and acceleration response behaviour of the vehicle and its occupants. Out of several different directions of crashes front impact is very dangerous and common. In the frontal impact passenger vehicle hits to any other object. In this event velocity of vehicle abruptly reduces by zero within very short period of time. This causes sudden movement of occupant against the vehicle and damage to the passenger and sometimes death. This can be avoided by increase the time duration of the impact i.e. reducing the overall deceleration. Airbags are the life saving equipments of the vehicle. These devices play an imperative role to reduce the occupant acceleration at the time of crash or accidents. Finite Element Analysis is used to simulate crash event. This study includes the effect of Airbags and during crash. Hyper mesh (Product of Altair Engineering) is used to simulate and analyze the frontal impact scenario.
