METHODS TO INCREASE FREIGHT CARS’ DISTANCE RUN BETWEEN REPAIRS BY UPGRADING CAR’S BOGIE
Abstract
The authors participated in MIIT University’s researches aimed at refining mathematical and computer models of cars were refined, describing a motion along railway lines with normalized irregularities in plan and profile. The models consider spatial oscillations of each node, details of solid body, structure, material properties, as well as predict abrasive wear of critical parts and components of a bogie. The article justifies a possibility to increase overhaul life of a car by a simple upgrade of a bogie model 18-100 from 160 to 250 thousand km, and by a comprehensive modernization – up to 500 thousand km.
