Sentence examples for measured wheel roughness from inspiring English sources

Magnitudes and wavelength contents of measured wheel roughness are compared with corresponding measurements of rail roughness.

Analytical studies using measured wheel and rail roughnesses have shown that the increase of the dimension of the contact area in the direction transverse to rolling can lead to 5 10 dB reduction in the interaction force between the wheel and rail.

When the two models are used to estimate the blocked interaction force between the wheel and rail for measured wheel and rail two-dimensional roughness distributions, however, the blocked force predictions are very similar even for wavelengths that are the order of or slightly shorter than the dimensions of the contact area.

To measure wheel freeness, each wheel was accelerated to a constant velocity, then the number of revolutions spun until stopping was recorded.

Overall sales of measuring wheels worldwide are unknown.

Previous to this, measuring wheels were custom-made devices.

Rail and wheel roughness have been measured and the track characteristics have been determined by rail receptance and wave decay measurements.

On most lines of the Dutch railway network, where a substantial amount of block-braked trains have rough wheels, the average wheel roughness dominates over the rail roughness.

Variations occur owing to varying wheel conditions including wheel wear, wheel shape, vibrations, and wheel roughness.

Therefore, reducing wheel roughness is top priority in the Netherlands.

The procedure for the selection of mitigation measures is based on numerical simulations, combining WRNOISE and IMMI software tools for noise prediction with experimental determination of the required track and vehicle parameters (e.g., rail and wheel roughness).
