Abstract

Object of research is development of a method of acoustic monitoring of traction transfers at carrying out of maintenance service of electric trains. On the basis of the developed technology reception and registration of acoustic signals of a reducer of trac-tion transfer is offered. Thus the corresponding wheel pair the motor carriage by means of a hydraulic jack rises above a head of a rail, and on the traction electric motor a feed from an extraneous low-voltage source of a direct current moves. When the wheel pair will reach stable rotation, registration of an acoustic signal on the case of a traction reducer, by means of the special gauge, with his subsequent record on the tape recorder is made. The method of allocation cyclic temporary making of a full acoustic signal on the basis of concurrence corresponding tooth's the big cogwheel and gear a traction re-ducer is offered. In researches the problem fractals the analysis of the received acoustic signals is formalized and the special program for her realization is developed. The tech-nical condition of a traction drive is offered to be estimated on the basis of fractals the analysis of the received acoustic signal on settlement value of a parameter of Hurst. Es-timated gradational borders of change of numerical values of this parameter which en-able are installed to determine working capacity of traction transfers. The received re-sults of such monitoring allow installing occurrence and development of defects in trac-tion transfers during operation of an electric train.
