Annotations languages:

It was proposed and investigated the usage of imbalance detection algorithms of information signal of vibroaccelerations sensors during dynamic tests of the rolling stock. This article describes software that implements the definition of spasmodic changes of signal properties by CUSUM procedure, Shyuhart’s algorithm and Lemon-Rozenblat criteria. Results of practical usage of the developed system for processing results of running approval test of rolling stock were represented.
