INFLUENCE OF LATERAL DISPLACEMENT OF BOGIES ON THE FREIGHT CAR DYNAMICS

نویسندگان

چکیده

Purpose. The work is aimed at determining the influence of lateral displacement a freight car bogie, taking into account value movement speed on its main dynamic indicators and interaction rolling stock track. Methodology. quantitative assessment was obtained by method mathematical computer modeling. design scheme takes peculiarities cars as part train: possibility all modes body vibration in space, transmission longitudinal force from neighboring vertical horizontal directions, technical condition individual parts their features, well various operating conditions. Findings. During research, model coupling five applied to study loading gondola Main track case transverse bogie when moving along curved sections were assessed. maximum possible values substantiated. Originality. train has been improved. In calculation schemes describing vibrations cars, bogies, lozenging side frames are taken account. makes it effect changing rotation angle central axis body, which turn leads bogies relative each other, For first time, investigated, wear assemblies with unevenness. Practical value. results can be used assess qualities track, units straight irregularities. application will contribute an increase stability conditions increasing travel speeds, allow developing for implementation resource-saving technologies transporting goods that meet safety requirements traffic.
