Sentence examples for rail surface in from inspiring English sources

Subsequently, the crack began to propagate in the rail surface in a U shape toward the gauge side in both the traffic direction and the opposite-traffic direction and into the rail toward the field side at an angle of approximately 20°.

With the assumption that the power spectral density of the unevennesses on the rail surface is in proportion to the third power of the wavelength, or to (wavenumber)−3, the amplitudes of the vibrations in railway tracks supported by rail-pads and roadbeds with various magnitudes of elastic constants are analyzed and the values for each one-third octave band are estimated.

White etching layer (WEL) is a frequently observed microstructural phenomenon in rail surface, formed during dynamic wheel/rail contact.

Secondary cracks initiated at an angle of 160° with respect to the rail surface and further bifurcated in tertiary cracks.

The model is defined in the time domain in order to introduce and correctly evaluate nonlinear and time-variant phenomena related to the contact model and boundary conditions which play a very important role in rail surface degradation phenomena.

The rail corrugation on rail surface is very frequent in all railway infrastructures and is also classified as short-wave defect (long wavelength irregularities are, instead, defined as irregularities of wavelengths of 300 mm or longer, that may be either geometric irregularities in the track or on the wheel, or irregularities of the track stiffness [10]).

In Fig. 2a, the value of H in the rail surface area is high as a whole and has small mutations.

The track area usually consists of rail, ballast, sleeper, and fasteners; their characteristics and H values are different in the detecting image, as shown in Fig. 2. (1) In Fig. 2a, the value of H in the rail surface area is high as a whole and has small mutations.

Rail-grinding machines run over the track to even out irregularities in the rail surface.

The separation of profiles f yz (y) = z yz w (y) + z yz r (y) is obtained from the sum of the cross-sections z yz w (y) of the wheel rolling surface and z yz r (y) of the rail surface by x = 0 in the contact plane.

It involves recoating the rail surface with a metal-reinforced epoxy in which the heating elements for de-icing would be encased and protected from moisture and corrosion.
