FIELD: instrument making.SUBSTANCE: invention relates to instrument making, particularly, to measuring devices for measuring and recording forces of interaction between wheel and rail. Device for measuring vertical and lateral forces of interaction between wheel and rail includes railway mounted axle, strain gages arranged on inner and outer side of wheel disk on both sides from axis on concentric diameters of inner side drive wheels and included in half-bridge circuit, strain amplifier, programmable controller, unit for signal transmission via radio channel connected to a unit for receiving signals and onboard computer. Tensoresistor on outer side of wheel disc are diametrically positioned in line with tensoresistors on inner side, and angle α between adjacent diameters on inner or outer side of wheel disc, on which there are diametrically opposite strain gages, ranges from 36° to 60° circular arc.EFFECT: high accuracy of measuring forces of interaction of wheel with rail due to reduced effect on measurement of vertical forces, transverse displacement relative to rail and expansion of frequency range of measured vertical and lateral (horizontal) forces occurring at contact of wheel on geometrical, butt and irregularities wavy irregularities on rail running surface.5 cl, 12 dwg |
