CALCULATION OF QUASISTATIC LATERAL FORCES ACTING BETWEEN WHEEL AND RAIL ON CURVED TRACK

BEREGNING AV KVASISTATISKE SIDEKREFTER SOM OPPTRER MELLOM KJUL OG SKINNE I KURVER

A nonlinear, quasistatic method for calculation forces acting between wheel and rail on curved track is developed by NSB. The method, which is based on the use of a digital computer, is developed for vehicles with two- and three-axle trucks with cross-connection. The following parameters can be nonlinear: effective conicity, angle of contact between wheel and rail, friction as a function of creepage between wheel and rail, and lateral stiffness of cross-connection between trucks. The method was checked against representative experiments and the results were found to be satisfying.
