Abstract The paper focuses on simulation, optimization & analysis of a Rear under Run Protection (RUPD) system under crash scenario. The basic objective is to improve the safety of the car and the occupants by designing the RUPD and car bumper. The choice of material and the structural design are the two major factors for impact energy absorption during a crash. It is important to know the material & mechanical properties and failure mechanism during the impact. 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. This analysis is a partial work of a major project wherein the RUPD will be subjected to static tasting with variable load distributions at different location on RUPD.Under-running of passenger vehicles is one of the important parameters to be considered during design, optimization & development of heavy vehicle chassis. In INDIA, the legal requirements of a RUPD are fixed in regulation IS 14812-2005which are derived from ECE R 58, which provides strict requirements in terms of device design and its behavior under loading that the device needs to fulfill for the approval of load carrying vehicles. Keywords: IS (Indian Standards), ECE R-58(Economic Commission Europe Regulation-58), Optimization, Simulated annealing _______________________________________________________________________________________________________
I. INTRODUCTION Heavy vehicles accidents represent a significant factor in the overall road accident scene. Analyzing the Indian problem (1995), heavy vehicle like a trucks with a gross vehicle weight Optimization & Development of Vehicle Rear Under-Run Protection Devices in Heavy Vehicle (RUPD) for Regulative Load Casesof more than 3.8 tonnes are involved in around 22% of the fatal road accidents and approximately 62% of these are car to truck accidents. The injury risk of accidents involving heavy vehicles appears to be far greater for occupants of opponent vehicles, especially for cars. And this risk increase in the case of car to truck frontal collisions.
