Method and the system for simultaneous measurements of Y and Q forces acting on a railway rail and for determination of the Y/Q forces ratio

摘要

Method for the simultaneous measurement of horizontal force Y perpendicular to the plane of symmetry of the railroad track and the vertical force Q and for determining the ratio of these forces indicated by Y / Q, characterized in that the measurement of the force between the wheel of the wheelset and the railhead, that is the vertical force Q are simultaneously performed by means of two force sensors 6 for measuring shear forces and the horizontal force Y perpendicular to the plane of symmetry of the railroad track by means of a force measuring device 1 for measuring transverse forces, wherein the force measuring device 1 is embedded in an opening in the web of the rail in the track, wherein the Opening in the web of the rail is made in the section between two adjacent sleepers,wherein two force sensors for measuring shear forces are embedded in two openings in the web of the rail on both sides of the force measuring device, the signals from the strain gauges used in the force measuring device 1 for measuring transverse forces being fed to a first electronic circuit U (Y), whereby the output signal comprises S (Y), the signals from the strain gauges used in the shear force measuring sensors being supplied to the second electronic circuit U (Q), whereby the output signal S (Q) comprises both signals S (Y) and S (Q) are supplied to a third electronic circuit U (S / Q), whereby the ratio of the forces Y to Q is determined, and the resulting signal is processed into an output signal S (Y / Q).
