摘要
System of measuring the force effect between the wheel of the railway rolling stock and the rail during ride of the rolling stock is based on detecting the deformations of the wheelset's wheel using a strain gauges system placed on one side of the wheel on one pitch circle which consists of Wheatstone complete bridges wherein the arrangement of the strain gauges system is decidedly defined by the diameter of the pitch circle R, the number of Wheatstone complete bridges, the openness angle of the bridge δ, the angular pitch of the bridges ϕ and the strain gauge's angle to the radial position β, wherein the highest accuracy of measuring of force FT is being achieved when angle β is approximately 45°, wherein during calibration the wheel (5) or the wheelset (6) rotating around its rotation axis is loaded by a rotating roller (15) which is by its circumference in contact with the wheel's (5) or the wheelset's (6) circumference, wherein the number of loading rollers (15) is two and each roller loads one wheel (5) of the wheelset, wherein thanks to its installation dimensions and construction the calibration frame is for calibration - loading placeable under the railway rolling stock (16) in which the wheel (5) or the wheelset (6) is embedded, wherein the transverse position of the loading roller (15) or rollers and support points can be changed by inserting of the reduction frame (20) of various widths for various rail gauges, wherein the calibration frame is mobile.
