The effect of vibrations on the pull-out resistance of a steel wire rope buried in a sand body: A small scale experimental approach

A landfall operation is conducted whenever a pipeline reaches the shore, during this operation the pipeline is pulled onto shore with the help of a steel wire rope. Allseas engineering has experienced several cases of landfalls during which the friction forces along the steel wire rope rose to excessively high levels. These cases occurred at...

Low Adhesion in the Wheel-Rail Contact

Adhesion, or adhesion coefficient, is given by the ratio of the longitudinal tangential (i.e., braking or traction) force over the normal force at the wheel-rail contact. The tangential force that a braking or tractive railway wheel can exert on a rail is limited by the friction coefficient available between the surfaces in contact for a given...

Investigating the lubricity and electrical insulation caused by sanding in dry wheel–rail contacts

The adhesion (or available friction) in the wheel–rail contact is the most important parameter for the braking and traction operation of rail vehicles. Since the beginning of railway transportation, sanding from the locomotive has been a common practice to enhance the wheel–rail adhesion. In recent years, sanding from electrical multiple units ...
