CONSIDERATIONS REGARDING THE IMPACT OF A PROTECTIVE BARRIER AND A PENDULUM
The paper presents the impact of a pendulum with a weight of 2780 kg and a road protective barrier used on the roads of Romania. Deformable parapets are very important to protect the pedestrians and the vehicles on our roads. The maximum dynamic deflection of the parapet, measured after the test was 0,240 m and 0,435 m of working width.
The barrier was deformed as expected. Damping elements have taken a large amount of energy during impact. The pendulum is used by researchers in this field. This is a very good way to track the behavior and damping elements of the barriers in the laboratory.
