Evaluation of operational performance parameters of rolling stock when driving over bumpy roads

Abstract

The current situation on the railway network of Russia and the East Siberian Railways in particular, the increase in the number of wagon cuts and unsatisfactory condition of the track and rolling stock, require the search for optimal solutions to these problems. Considering this topical subject it is necessary to touch upon the issues of modern strategies and trends in the development of railway transport with the introduction of modern technologies and technological equipment. As a result of a detailed consideration of the cause-and-effect relationship of the occurrence of factors affecting the dynamics of the car passing the track irregularities, the starting point will be an in-depth analysis of the system of interactions between the wheel and the rail. This analysis will make it possible to objectively assess the causes of existing problems in the field of operation, describe the emerging phenomena with a sufficient degree of justification, offer progressive topical solutions and possible promising developments in this industry. Turning to the statistics on failures over the past 3 years, one can trace the growth of malfunctions associated with defects in the rolling surface of wheel sets. Indeed, an increase in the speed of rolling stock, and in the volume and quantity of transported goods resulted in an increase in the intensity of rolling stock operation. Consequently, there was an increase in loads on the main components of the rolling stock and in the intensity of parts wear.
