NF F07-101 Railway Applications - Schock Test by Throwing Ballast Simulation

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of NF F07-101 test. Railway vehicles moving on ballasted lines during operations are exposed to the impacts of the stones that make up the ballasts in question. Often times, their high speed of over 200 km/h causes the air to lift the stones and throw them towards the equipment and structural parts on the subframe.

The impact of the ballast can cause damage to the affected area and in some special cases can cause a serious incident. The next mentioned inconvenience is noise from the air and impacts. Due to these points, many manufacturers equip their products with additional protective covers fixed on the subframe to isolate them from external factors.

This protection can be accomplished in a number of different ways, but mostly using a special steel sheet or a polymer composite sandwich. Composites offer some advantages over steel in that they reduce noise better and are lighter. That's why modern trains are often protected with this material.

On the other hand, the use of polymer composite materials to protect the chassis from the aggressive environment makes it necessary to be absolutely sure of their properties, as they are anisotropic. Therefore, simulations and real tests are needed to verify the effectiveness and impact resistance of the designed cover.
