Abstract: Automotive vehicles play a vital role in our daily life. Major accidents occur due to frontal collisions which cause serious injuries and disabilities. To prevent the collision some improvements, need to be done for the vehicles especially the safety measures to reduce the injury level of the occupants the nature of the vehicle structure is the ability to convert kinetic energy to deformation of the structural parts which results intrusion of the front part of the vehicle. This will severely harm the occupants who cannot able to withstand the heavy load during the collision. To prevent this sudden impact, the passive safety system is implemented to reduce the deceleration loads (G-Force). This research is based on the development of the occupant safety during the frontal collisions. In practice, the body structures include the front structure with crumple zones to absorb the kinetic force energy and during the impact the vehicle should maintain the integrity of the passenger compartment while controlling the impact deceleration pulse. The aim of the research is to reduce the stiffness in the front part of the chassis or to create a crumple area to deform the structure in a short time (milliseconds) and to absorb the impact energy in a controllable way. The structural rigidity should also be consistent with ride and handling and must be compatible with other vehicles on the road so it is not too soft or too aggressive. The main objective of the research is to reduce the frontal impact of the occupant safety by measuring the Intrusion and deceleration pulse with crash avoidance and crashworthiness.
