Modeling and Stress Analysis of Impact Attenuator for Vehicles Protection

Abstract

In high speed race car having An impact attenuator, also known as a crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision or sudden happen accidents. So In this project Impact attenuators are designed with honeycomb structure to absorb the colliding vehicle's kinetic energy or sudden acted forces.Honeycomb Impact attenuator is a deformable, energy absorbing structure located at the front of the vehicle whose sole purpose is to absorb the kinetic energy of the high speed race car and limit the deceleration acting on the human body. Also discusses the sudden crash analysis of the designed attenuator honey comb structure in order to determine the safety of the design. The design with the help of the computer aided software catia. Dynamic and structural analysis and stress and strain, von misses stress, equivalent stress, total deformation is anlyse with the help of ansys .whereas Initial requirements of used materials are taken advanced carbonfiber reinforced plastic materialsafter completion of the analysis comparison the existing material and new materials of honey comb stracture.
