Experimental studies of vibrations of asynchronous electric motors (EMs) of the electric bus traction electric drive are carried out in the paper. The presented studies are based on generalization of the diagnostic features of vibration characteristics and statistics concerning the limiting values of vibration parameters of EMs and their dependence on the technical condition. The analysis of the obtained results allowed us to determine the permissible vibration levels of EMs in the frequency range from 5 Hz to 10 kHz. The method of diagnosing EMs traction electric drive according to the indicators of vibration levels is developed, which allows to evaluate their technical condition. The values of the permissible vibrational accelerations of the electric bus EMs are determined, which enable to estimate their technical level. This method allowed to develop classes of evaluation of the EMs technical condition by the level of their vibration, which makes possible to predict their resource.

The powerful means of improving the economy of locomotives during modernization is introduction of electric speed and power controllers, including the ability to control the moment of the fuel supply start. In the depot of the South Railway (Kharkiv, Ukraine), the electronic controller for the speed and power of the diesel generator and standard hydraulic speed and power controller were compared by operational tests at two sections of the freight mainline locomotive of 2TE116 type. The tests were being carried out under real operating conditions during 1-year period. The results showed reduction in fuel consumption in operation up to 6% on a diesel generator equipped with an electronic controller. The rate of the increased operational fuel economy can be given in technical materials only in relative units. The obtained results can be used in substantiating the application of various technical control and management systems.
