Experimental Determination of Wheel and Guiding Forces on the Tracks

摘要

Force interaction between a railway track and a vehicle affects the safety, comfort, and last but not least, maintenance costs. Train of wagons incidence on track in both transversal and vertical direction is simplified by the qualifying of force wheel (FQ), guiding (FY) and perpendicular and transverse acceleration. An experimental basis for dynamic determination of vertical, FQ, and lateral, FY, forces at the wheel using strain measuring in the foot of the rail is given. Measurements of the dynamic forces during passing the train are normally very costly and uneasy. This method consisting of measuring strains at selected points of the rail profile is very simple and therefore interesting.
