INVESTIGATION OF FRICTION COMPOSITE MATERIAL MICROSTRUCTURE FOR ELECTRIC DRIVE COUPLINGS
Complex research of the frictional composite material microstructure including the computer metallography executed with the help of Image.Pro.Plus 5.1 software, and mechanical tests at the special panel with the SP-6 electric drive is conducted. The authors define the optimum microstructure of material and the modes of its agglomeration providing stable operating conditions of frictional disks of the electric point machine couplings. Stable operating conditions of the frictional coupling were estimated depending on current intensity consumed by the electric motor, and its fluctuations when slipping frictional disks.
