Shegedin P. Сomputerized diagnostic system of technical state parameters of the traction rolling stock

The research is devoted to the development of computerized diagnostic system of technical state parameters of the traction rolling stock. The properties of information signals recorded in special and dynamic tests have been investigated in the research. The methodology of testing for determines damping characteristics and algorithms of calculation of the damping parameters are demonstrated. The research offers and investigates the usage of imbalance detection algorithms of information signal of vibroaccelerations sensors during dynamic tests of the rolling stock. Developed the software that implements the definition of spasmodic changes of signal properties by CUSUM procedure, Shyuhart's algorithm and Lemon-Rozenblat criteria. Approbation of the system was carried out in the processing of data obtained from dynamic testing of high-speed train.
