The paper is aimed at determining possibility to provide reliable condition assessment of rotary units of mechanical part of rolling stock during operation and with acceptable cost of single diagnostic act. To reach that goal one need to develop a list of experimental researches of vibration acoustic processes and to create an experimental device for signal measurement.
The paper presents the results of development of the experimental device used within the framework of an integrated program of research of vibroacoustic processes to obtain data on vibration of mechanical components of rolling stock working in real operating conditions. The device enables prolonged continuous stream recording of signals from transmitters, in particular, from vibration sensors in the band to 900 kHz.
Results of the analysis of data obtained using the experimental device have been used as a basis for train component diagnosis algorithms, implemented in onboard condition monitoring systems COMPACS®-EXPRESS-3, installed on modern rolling stock.
