In the present research work we are focusing on side under-run protection devices protect road users such as pedestrians and cyclists from slipping sideways under the wheels of trucks and trailers, and can also improve the aerodynamic performance of heavy vehicles. The basic objective is to improve the safety of the car and the occupants by designing the Rear Under-run Protection Device (RUPD) and car bumper. The choice of material and the structural design are major factors for impact energy absorption during a crash. This study concentrates on component functions, geometry, behavior of material and other parameters that influence the compatibility of the car bumper and rear under run protection device. The analysis was carried out using Finite Elements software SOLIDWORKS. This analysis is a partial work of a major project wherein the RUPD will be subjected to static testing with variable load distributions at different locations on RUPD. After the analysis, the pattern of the part is obtained using Rapid prototyping machine. This can be used for Machining/ casting of the original part. Rapid Prototyping (RPT) can be defined as a group of techniques used to quickly fabricate a scale model of a part or assembly using three-dimensional computer aided design (CAD) data.

The basic objective is to improve the safety of the car and the occupants by designing the Rear Under-run Protection Device (RUPD) and car bumper. The choice of material and the structural design are major factors for impact energy absorption during a crash. This study concentrates on component functions, geometry, behavior of material and other parameters that influence the compatibility of the car bumper and rear under run protection device. The analysis was carried out using Finite Elements software SOLIDWORKS. This analysis is a partial work of a major project wherein the RUPD will be subjected to static testing with variable load distributions at different locations on RUPD. After the analysis, the pattern of the part is obtained using Rapid prototyping machine. This can be used for Machining/ casting of the original part. Rapid Prototyping (RPT) can be defined as a group of techniques used to quickly fabricate a scale model of a part or assembly using three-dimensional computer aided design (CAD) data.
