The wheel-rail acting force between the train wheels and the steel rail is an important parameter for describing the wheel-rail relationship, and the accurate acquisition of the wheel-rail force plays an important role in designing the railway track and the lower basic structure. The wheel-rail force comprises a wheel-rail transverse force and a wheel-rail vertical force, the wheel-rail transverse force is a force of a wheel acting on the steel rail in the transverse direction of the rail and perpendicular to the steel rail section symmetry axis, and the wheel-rail vertical force is a force of the wheel acting on the steel rail in the direction parallel to the steel rail section symmetry axis.
According to the ground test method for the transverse force and the vertical force of the wheel rail (TB/T24289-2016) in the railway industry standard, the wheel rail force is tested by a shear stress method, and data acquisition is mainly carried out by sticking strain gauges on a steel rail. When the transverse force of the wheel rail is tested, the strain gauge is adhered to the upper surface of the rail bottom at the position 20mm away from the bottom edge of the rail on the bilateral symmetry section of the central line between the adjacent steel rail supporting points, the distance b between the strain gauges is 160 mm-240 mm, and the direction of the strain gauge forms an angle of 45 degrees with the longitudinal direction of the steel rail.
When the vertical force of the wheel rail is tested, the strain gauges are adhered to the two sides of the steel rail and on the neutralizing shaft of the bilateral symmetry section of the central line between the adjacent steel rail supporting points, the distance b between the strain gauges is 160-240 mm, and the direction of the strain gauge forms an angle of 45 degrees with the longitudinal direction of the steel rail. Meanwhile, the patch center lines of the wheel-rail transverse force and the wheel-rail vertical force need to be overlapped so as to ensure the accuracy of the calculated values of wheel-rail force derivative parameters (derailment coefficient, load shedding rate, wheel-axle transverse force and the like). Therefore, the accurate and quick positioning of the patch position is a precondition for the correct installation of the wheel-rail force test sensor.
Therefore, a positioning device for a wheel-rail acting force test sensor is needed to realize accurate and rapid positioning of the patch position.
