<p>Nowadays, the development of safety systems for passenger protection in the automotive industry relies heavily on numerical simulations. FE simulation was widely used to study the sensitivity of design parameters and their influence on costs and/or overall weight in new car models through the inspection of different scenarios developed. In this article, crash simulations were conducted to simulate a car accident via the finite element method. The aim was to analyze the performance of a car structure deforming during the collision in the presence of dummy, belted or not, to determine the degree of safety provided to the occupants of the car. The CAD model of the car and the dummy was made using LS-DYNA software; the collision impulse of the vehicle and the speed of the driver's seat were observed and compared. Various incoming speeds were taken into account when the car was modeled to crash into a wall.</p>
