Özet
Collision between passenger car and heavy vehicles are one of the most
dangerous accident type because of the size difference. Rear underrun protection device consisting of a horizontal beam and
structural support members and installed in the rear of the truck is used to
prevent penetration of passenger car. In this paper, a new rear underrun
protection device was designed. Three different support bracket thicknesses
that vary with 4-6 mm whereas investigated and their crash performance and
structural integrity were compared to each other. RUPD finite element
models were created and analysed for Dodge Neon (1996) collided at 63 km/h
vehicle impact speed under full overlap crash scenario. Abaqus/Explicit dynamic
analysis that is special tool for highly non-linear Dynamics phenomenon was
used for the analyses. The results showed that the new
RUPD design with 6 mm support bracket thickness reduced both axial deformation
of RUPD by %56.3, penetration of passenger car by %20.7 and enhanced CFE by
%7.92. The optimum support bracket thickness was determined for the new
developed RUPD against vehicle collision.
