From the past few years there are many accidents happening passengers are getting injured even after the deployment of the airbag. This is mainly due to the out of position of passenger and not wearing seat belt. The Head Injury Criterion (HIC) is used to assess passenger safety during a collision. The Head Damage Criterion (HIC) model was created to quantify the risk of head injury in accident conditions. Using a computer algebra system (here LS-DYNA) capable of analysing results from a real-world car collision test. In this project, Airbag simulation along with human head foam is carried out. Nylon material is used for Airbag and material properties are given to the airbag. Human head foam which is downloaded from LSTC website is used. The human head foam is aligned in the direction of airbag deployment and made to strike airbag at an initial velocity of 35mph at different positions of the airbag. The primary goal of this research is to evaluate the performance of airbag deployment using finite element methods (FEM) to manage various collision scenarios while lowering the HIC value.
