Grinding Management of Rail Profile Based on Abnormal Hunting of High-speed Train

机车电传动, 2020
To study the influence of the polished depth of rail profile at the gauge angle on the low-frequency vibration of high-speed train, a group of rail profiles were obtained by interpolating between the standard CN60 profile and the measured rail profile ...

ANALYTICAL DETERMINATION OF THE REDUCED ROTATIONAL RESISTANCE COEFFICIENT OF THE CONSTRUCTION MACHINE SLEWING GEAR

Nauka ta progres transportu, 2019
Purpose. Designing new models of construction machines is closely related to the development of slewing gear, and that, in turn, has a drive whose power and dimensions depend on the rotational resistance and the reduced friction coefficient in the units.
