Increasing mine train mass by means of improved efficiency of service braking

Abstract

Methods to increase mine train mass allowable for braking have been studied. Possibility to use rail magnetic brakes to improve efficiency of dynamic braking has been analyzed. Mathematical model of the train braking involving a magnetic rail device to increase locomotive axial load has been proposed. Results of the braking calculations with the use of the modeling results have made it possible to conclude on the fact that a magnetic rail device used to increase locomotive axial load allows improving considerably braking characteristics of a locomotive and increasing mine train mass allowable for braking.
