A study of the contact of the wheel with the rail for various conditions of freight car

Abstract

Abstract The paper presents the results of calculations of the parameters of contact interaction of the wheels of a freight car with R65 rails (wheel wear rate, areas of wheel contact spots with rails, friction power capacities in contact spots) for various operating conditions on the Russian Railways road network. The choice of groups of operating conditions was made on the basis of the methodology for ranking the characteristics of the main roads in the plan and profile. The quantitative values of the parameters of contact interaction were established, and their comparative analysis was carried out for the conditions under consideration.
