Abstract—The paper focuses on simulation and 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 and 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. The
analysis was carrying out using Finite Elements software (LS-Dyna), Meshing tools by Altair
Hyper mesh and Modeling on Pro-E. 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. The analysis establishes the method and parameters of the simulation on modeling
and analysis software used by demonstrating the energy absorption pattern in bumper and
RUPD during frontal crash of a car with different design parameters of RUPD.
