Sensor system of detecting defects in wheels of railway vehicles running at operational speed

A number of deviations from the theoretical idea of the expected mechanical interaction between railway vehicles and track are observed in the real operation environment. The load transmitted by each wheel in static and dynamic aspects has become an object of increasing interest. A team of experts from the Todor Kableshkov University of Transport and the Technical University of Sofia who participated in several national and international projects have proposed particular solutions for creating a model to develop the necessary system of sensors as a main component of the systems of control on moving trains. This system of sensors is the subject of the paper presented.
