ON THE IMPACT OF THE CHARACTERISTICS OF ROLLING STOCK ON SHUNTING RESISTANCE OF RAIL CIRCUITS

Abstract

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT The effect of a combination of rolling stock characteristics, including wheel set electrical resistance, axle/wheel load, vehicle speed, electrical resistance of «wheel-rail» contact, has been studied. The data of three reference vehicles - a biaxial rail car, a four-axle conventional and a four-axle high-speed locomotive were studied. Two approaches are used which are deterministic and probabilistic ones (Monte Carlo method). On their basis, the process of detecting static and dynamic shunts for three ranges of speeds of movement and two degrees of rail pollution with an insulating film is provided. Keywords: railway, rail circuit, track circuit, electrical resistance, static shunt, dynamic shunt, rolling stock.
