Design and Analysis of a car Bumper Using Springs

Automotive design with economy and safety has been a great challenge to design engineers. The safety of the passengers and vehicle during vehicle crashes can be ensured to a certain limit by using good bumpers. Bumper is an important part of vehicle which acts as one of the safety part of vehicle, now a day's bumper is used in vehicle which directly connected to chassis of vehicle. So that when accidents are happened the force that transfer to other parts of vehicle through linkage There is no mechanism to drop that linkage and to absorb that impact forces. So that the development of a new bumper system by springs. Spring is used to minimize the impact of accidents and it will resists or absorbs impact forces. The new bumper system will be design in CATIA and structural analysis is done by ANSYS. For structural analysis of the bumper materials like Glass mat thermoplastics (GMT), carbon fiber composite and aluminum B390 materials are used.
