Research into resistance to the motion of railroad undercarriages related to directing the wheelsets by a rail track

Abstract: Виконано аналіз нового напрямку енергозбе-реження на залізничному транспорті, основано-го на зменшенні складової опору руху, пов'язаної з втратами потужності на спрямування екіпажів рейкової колією. На основі математичного моде-лювання руху вантажного напів-вагона уточне-но залежність опору руху в кривій від швидкості. Отримано залежності питомого опору руху в кри-вій від параметрів колії і ходової частини екіпажу Ключові слова: залізничний транспорт, тяга поїздів, ресурсозбереження, опір руху, спрямуван-ня ек… Show more

“…Stress values, that have been measured by strain gauges does not exceed the permitted levels and no residual deformations and cracks were detected. With this research and development subjects deals other publications too [5][6][7][8][9][10][11][12][13][14][15][16][17].…”

“…For example, at a speed of 40 km/h, the adhesion force is reduced to 7%, from the discrepancy of the wheel diameters to 1% [17,18]. An analysis of the scientific literature [19][20][21][22][23] suggests that the redistribution of loads is strongly influenced by spring suspension. The unevenness of the static load on wheel pairs of the same axle reaches 10% with different spring rigidity, 5% -due to the error of the weights.…”

“…-profiling surfaces of contacting bodies; -calculating relative velocities at the points of contact; -determining contact forces. Papers [31,32] present requirements for a modern rolling stock with a detailed consideration of the corresponding characteristics for freight railway cars. However, the work does not indicate the potential and ways to improve the dynamic characteristics of the rolling stock and especially the safety performance in various states of the cars.…”
