Embodiment 1
[0026] In one embodiment of the present invention, the steps of the continuous testing method for wheel-rail moving vertical force of the present invention include:
[0027] Step S101, dividing a plurality of measurement intervals on the load-carrying rail, including two support sleepers within the range of a single measurement interval, and setting a first pressure sensor and a second pressure sensor on the support surface between the two support sleepers; The first shear force sensor and the second shear force sensor are arranged on the bearing rails on both sides of the adjacent sleepers, so that the measurement areas of the shear force sensors in adjacent measurement intervals intersect.
[0028] Step S102, run the counterweight inspection vehicle according to the set speed on multiple measurement intervals carrying the rails. During the operation of the inspection vehicle, the multiple measurement intervals respectively record the first pressure sensor value R1 and the sec...
Embodiment 2
[0033] Figure 6 It is the second embodiment of the present invention, and the characteristic of this embodiment is that the adjacent shear sensors (2) of the two measurement areas are arranged crosswise in the adjacent sleeper boxes. It can be seen from the figure that the first measurement area is composed of pressure sensors (1) R1, R2, R3 and shear force sensors (2) Q1, Q3, and the measured vertical force P of wheel-rail movement is: P=Q1+R1+ R2+R3+Q3; the second measurement area is composed of pressure sensors (1) R3, R4, R5 and shear sensors (2) Q2, Q4, and the measured vertical force P of wheel-rail movement is: P=Q2+R3 +R4+R5+Q4. Wherein the distance between the shear force sensor (2) Q2 and Q3 is greater than the length of the blind area measured by the shear force sensor, and the distance between Q2 and the adjacent pressure sensor (1) R2, R3 and the distance between Q3 and the adjacent pressure sensor (1) R3 The distance between R4 and R4 is greater than half of t...
