DYNAMICS OF PASSENGER ELECTRIC LOCOMOTIVE TRACTION DRIVE

Abstract

Problems with mounting of electric locomotive traction motors threaten railway safety. The authors analyze the nature of destruction of fastening bolts and brackets, and formulate a number of working hypotheses explaining causes of destruction. The theoretical significance of the article is to examine the conformity of a design scheme used to determine forces acting on elements of the supporting structure, with actual reactions occurring in the bearings. Particular attention is paid to possible emergence of periodic disturbances in traction drive from clutch taking into account gyroscopic moments, occurring when it is rotating. On the basis of dynamic calculations conclusions are suggested about the causes of destruction of mounts and about what scheme of traction motor fastening to the bogieframe is rational, especially for high-speed modes.
