Abstract

Purpose. With the advent of new designs of freright cars the task of designing the more modern bogies, assessment of their dynamic properties depending on the type and structure of pecularities, accounting the axle loadings, providing the dynamic and running characteristics, meeting the conditions of impact on the track, stability, and frame forces intensity etc. becomes especially important. In order to launch the new production into manufacture and to assess the dynamic properties using different designs of bogies the running testes were conducted. They allowed one to compare the dynamic performance of the new bogie with the existing models. Methodology. The study was conducted using the method of numerical integration and mathematical modeling of dynamic loading of freight cars using the software package «Dynamics of Rail Vehicles» («DYNRAIL»). Findings. The results of studies of dynamic characteristics of open cars with new and worn wheels of bogie models 18-9771, 18-9770 and 18-578 in graphical and tabular form are presented. All figures are within the normative values and do not exceed the maximum admissible ones. Originality. When designing the bogie for loading 23.5 t/axle almost all available technical solutions to improve the characteristics of the freight car bogies (elastic bearers, cassette bearing in axle boxes, axle boxe adapter of original design, bilinear central spring suspension, etc.) were used. Practical value. As a result of the engineering works on projecting and manufacturing of the improved designs of freight car bogies a new design was received. It is highly competitive with the dynamic qualities of the best ones. Made choice of rational values of elastic-dissipative parameters of the bogie allows one to create standard series of running gears for freight cars for promising operating conditions.The results are of practical importance. They have found reflection in the number of author’spublications in special and semi-populareditions.
