Abstract
To mitigate the degree of damage to passengers caused by automobile collisions, a friction damper was built and used in experimental tests to test its effectiveness in impact energy attenuation. The study revealed that energy absorption capacity of a bumper can be improved with the addition of a friction damper. The results revealed that the addition of the friction damper to an automobile bumper to give a bumper-damper system could attenuate about 32.5 % more energy than with the bumper alone. It can be concluded that the effectiveness of automobile bumpers to withstand impact of vehicles by absorbing the kinetic energy from the impact can be improved with the use of a passive friction damper. That is, a passive friction damper system could be used to attenuate more road vehicle impact energy in collisions.

Summary
Road traffic crashes and their effects are quite complicated and expensive. Costs attributable to this include social costs, medical costs, loss of production, human costs, material costs, settlement costs and traffic jam costs. Road traffic accident costs Ghana US$ 165 million annually, which is about 1.6% of its Gross Domestic Product (GDP) [1]. Appiah [2] estimates that about 4 people get killed daily and there are 1600 fatalities annually in. How to cite this paper: Agyei-Agyemang, A., Obeng, G.Y. and Andoh, P.Y.
