CONSIDERATIONS REGARDING THE WORKING
WIDTH OF ROAD RESTRAINT SYSTEMS AT
THE IMPACT WITH A SPHERE
This paper presents the simulation of the behaviour of two types of
road restraint systems on impact with a sphere in different points from the pillar
axis. The working widths of the restraint systems during collisions are
presented. The working width is very important because it characterizes the
parapets during impact. The simulations were performed with the help of finite
element software using Altair Hyper Works modules.
Keywords: displacement of parapets, road restraint systems
