Kravchenko K. The grounds of increase backlogs of locomotive hauling qualities and its realization by the management of sliding in the system of wheel with a rail

The thesis is devoted the questions of increase of locomotive hauling-couplings qualities by the management of sliding in the system of wheel with a rail. The scientific and technical task of choice of parameters of carriage of hauling rolling stock and friction interface management in the system "wheel-rail" is decided due to the redistribution of loadings on the wheelpairs of locomotive, increase of rolling friction coefficient and accounting of moment TED difference in composition of vehicle. The size of change of stress of additionally load device in the process of exploitation on the basis of using of the got analytical dependences of the coefficient of the use of coupling weight from the structural and operating parameters of locomotive is specified. Theoretically and experimentally the using of designed sandy system, based on electrization of abrasive particles, which are given in the contact of wheel with a rail which diminishes the size of sliding and improves hauling-couplings qualities of locomotive is grounded. Results of researches and the construction of additionally load device on a diesel-locomotive shunter TEM103-001 of public corporation "HC"Luganskteplovoz" are introduced. Keywords: locomotive, additionally load device, sandy system, selection of TED, imitation design, coefficient of coupling weight using, coefficient of rolling friction, sliding, electrization.
