Comparison of Requirements for Standards of Different Countries to Assessment of Freight Car Dynamic Qualities and Impact on Track

Purpose: To analyze and compare the requirements of State Standards Russia, countries Europe North America to assessment dynamic qualities freight cars, their impact on railway track. Methods: Review analysis various conditions pursue testing cars a track, indicator permissible values made it possible form most representative calculated cases for simulation crew motion along construction tracks (straight, curve sections) study car dynamics with help computer modelling in program complex "Universal Mechanism". Results: The comparison country’s behavior is made. Using methods, oscillograms indicators (forces, accelerations, coefficients) universal gondola car, installed bogies 18-100 model, at its were obtained. advantages flaws used approaches assess qualities, track are shown. Practical significance: work obtained results can be improve system purpose safety Russia.
