A study of the impact attenuator

The impact attenuator provides a charge channel for transverse and vertical loads in the event of off-center and off-axis collisions. The impact attenuator is distinguished by the concentration of energy dissipation in a limited zone and the recognition of the system by a static body movement. The impact attenuator minimizes vehicle frame damage and protects the driver from personal injury during the collision, according to the study. The impact dimmer's crush can absorb kinetic energy and evenly transfer low load to the remainder of the system. To understand the behavior of vehicle impact crushing, this paper examines academics’ work in the areas of design and impact mitigation analysis. The researchers’ geometric structure and material choice for the impact attenuator are briefly described first, followed by the FEA analysis and experimental testing techniques. The experimental and simulation experiments will be split into three groups: test, simulated test, and comparison.
