Vehicle safety is one of the major research areas in the field of automotive engineering. The car industry is developing new systems of passive and active safety and techniques to improve vehicle occupant safety. To reduce the cost of development and testing of new security architecture, it is recommended to use for the evaluation of simulation calculations accident early safety behavior under vehicle impact test. One of the devices are intended to reduce the damage done to the vehicle structure and possible injury to passengers as a result of the collision is the impact attenuator. The purpose of this project is to identify different materials and structural design for low cost impact attenuator design and perform crash simulation of impact attenuator in low speed impact. This requirement was completely satisfied with the final configuration of the impact attenuator. The main aspects of the research have been pointing out to find the optimal evolution of the kinetic energy during a front impact, with the lowest initial decline. In this report, the design concept of impact attenuator is discussed. The selection of impact attenuator as the platform to be develops largely due to less energy impact. The experiments were designed and performed to find the impact properties of honeycomb sandwich panels and to find the difference in properties of different design variations. Impact tests were performed on aluminum honeycomb sandwich panels of different thickness to investigate strength.
