Abstract

Under-running of passenger vehicles is one of the important parameters to be considered during design and development of truck chassis. "Rear under run protection device (RUPD)" is used to offer safety in case of rear impact and rear under-running of the passenger vehicles to the heavy and medium duty trucks. As per ECE regulation 58 RUPD is statically analyzed but we have performed its dynamic analysis in order to have the knowledge of the damage caused by rear impact in real life situation. Here we have suggested a modification in existing RUPD design. Maximum deflection and stresses in both existing and modified design are compared using FEA in LS-Dyna. Comparison clearly shows the necessity of improving the design.
