Design of an Extended Bumper for Mine Haulage Trucks

摘要

This report presents extended bumper designs for 170-ton rear dump haulage trucks used in the mining industry. The extended bumper designs are to provide operator protection in the event of rear-end collisions between two trucks. The bumper designs are a result of studying critical truck characteristics important in rear-end collisions and haulage truck accident data, as well as the dynamics of a collision. In addition, existing extended bumper designs were analyzed and evaluated.
