Abstract

Heavy vehicle safety is a serious matter for road transport authorities. Although their numbers make up only a small percentage of motor vehicle registrations. This is not to say heavy vehicles are always at fault but their size and mass makes any crash a serious one. Improvements to heavy vehicle design and safety features have made a meaningful contribution in reducing the number and severity of crashes. Currently there are a wide range of crash avoidance and harm minimizing technologies available on the market that have the potential to improve safety. There exists a large mismatch between the bumper of a passenger vehicle and the ground clearance of heavy vehicles. During collisions between the car and the side of the heavy vehicle, a large amount of intrusion is observed in the passenger compartment due to under ride. The result of these collisions often leads to injuries or fatalities. This research aims to develop side under ride protection devices and rear under ride protection device to eliminate the incompatibility between the small vehicle’s bumper and bottom of the trailer or box of the straight truck. To successfully design these guards, a procedure for analysing the effectiveness of the under ride protective device during a side crash was implemented by using the Finite Element Method within Catia V5 package. Based on this thesis, shows that cross section of solid bar is more better than for hollow bar.
