Abstract
EN: Abstract. A freight wagon is a collection of a large number of parts and assemblies that form a single
structure. During wagon operation, there are gradual changes in the characteristics and parameters of its
structural elements. That is, the parameters of its constituent elements change – their numerical values
increase or decrease that result in a change of the unit’s technical state, and, in turn, affects the totality of
its performance. Gradually accumulating, the changes in the parameters of the structural elements of a
wagon reach such a level that radical, sometimes abrupt qualitative change occurs. A malfunction that has
not been repaired timely may lead to a failure of a wagon structural element, which, in turn, may result in
rolling stock derailment. It has been established that the loss of stability of freight wagons during their
movement is most often due to their unsatisfactory dynamic properties, which can be explained by design
features and technical state of running gears. In this regard, the authors of the article have developed an
algorithm for investigation technical state of running gears of freight wagons and determined the effect of
their parameters’ deviation on rolling stock operation with possible further derailment.
