Sentence examples for derailment coefficient from inspiring English sources

Besides, the standard UNE-EN 14363 [28] establishes that the wheels with worn flanges may derail when the derailment coefficient is over 0.4.

Large gaps between two simply supported girders during earthquakes will increase the train derailment coefficient, and thus a reduction in the eccentricity between two girders can enhance the safety of moving trains.

a Derailment coefficient.

Hence, the value of 0.4 will be set as the limit derailment coefficient in this study.

As depicted in Fig. 10, derailment coefficient remains far below the limit of 0.4.

The derailment coefficient increased with the distance along which fasteners fail.

For the cases of a perfectly smooth rail with or without seismic loading, the train derailment coefficients are almost independent of train speeds.

The maximum derailment coefficients are quite linear in proportion to the peak ground acceleration (PGA) of the earthquake, if the structural behaviors and dynamic soil properties are not nonlinear.

Additionally, because the first train natural frequencies are often in the low frequency range, large pier stiffness producing high bridge natural frequencies can confine the train derailment coefficients near a normal value, even in the resonance between bridges and earthquakes, so we suggest that large pier stiffness should be used to ensure the safety of moving trains during earthquakes.

This coefficient is used to evaluate the risk of derailment of a railway vehicle by comparing its value with the so-called limit derailment coefficients, which depend on many factors according to the derailment mechanism considered in each case.

The derailment type depends on the combination of the horizontal and vertical forces, the flange angle and the friction coefficient.
