Design and development of rear under ride protection device (RUPD) with improved energy absorption using ANSYS

Abstract

Every year thousands of vehicle occupants are killed or injured due to road accidents. Out of which 8% are due to large truck accidents. Truck under ride accidents represents major part of the truck related accidents. Rear Under ride Protective Device(RUPD) of the truck is the main structure for absorbing the energy of collisions during rear impact. It is essential to improve the energy absorption characteristics of RUPD due to poor road conditions and primitive passenger safety systems in India. The current project is aimed at improving the energy absorption capacity of RUPD, for that two different designs are made and analyzed for improved deformation and strain energy storing capacity. The analysis was carried out in ANSYS and results are evaluated between two models for improvement in the deformation and strain energy storing capacity.
