Abstract

The object to configure a system for measuring loads during the wheel/rail contact of rail vehicles in such a manner that the occurring forces and/or torques can be measured in a reliable and realistic manner is solved by the present invention. Between the rail foot and the measuring device, at least one elastic element is arranged which has an elasticity which simulates the elasticity of a ballast bed. By means of the measuring system according to the invention, on the one hand, realistic conditions of a track system can be simulated and, on the other, a high metrological reproducibility of a load situation can be achieved.
