Bumpers are structural components installed to reduce physical damage to the front and rear ends of a light/ heavy motor vehicle from Low-speed collisions. Damage and protection assessments are the commonly used design criteria in bumper design. For damage assessment, the relative displacements representing stiffness performance are examined and crash test will be done. The purpose of a crash analysis is to see how the car will behave in a frontal or rear collision. In this paper, impacts and collisions involving a car bumper beam model are simulated and analyzed using Hyper works software. The bumper should support the mechanical components and the body. It must also withstand static and dynamic loads without undue deflection or distortion. The given model is tested under frontal collision conditions and the resultant deformation and stresses are determined using hyper works software. The crash analysis simulation and results can be used to assess both the crash worthiness of current bumper and to investigate ways to improve the design. This type of simulation is an integral part of the design cycle and can reduce the need for costly destructive testing program.
