摘要

ufeffprincip system for measuring force effects between wheel rolling stock and rail riding rolling stock consists in detecting deflection wheels of a wheelset through tenzometricku00e9ho system located on the one hand, on the one hand wheels on one wheel pitch circle and composed of wheatstoneovu00fdch full bridgesthe arrangement of the tenzometricku00e9ho system is clearly defined pitch circle radius r, the number of wheatstoneovu00fdch full bridges, bridge.delta. aperture angle, angular pitch.fi. bridge since the radial position and angle rotation tenzometru.beta.configuration of the system is optimized for the detection of tenzometricku00e9ho tangenciu00e1lnu00edch force ft, which is obtained by making tenzometru from radial position of angle. beta., with the highest measurement accuracy is achieved with the force ft angle. beta. around the value of 45 degrees.in the calibration is a wheel (5) or (6) of rotating around its axis of rotation with a rotating pulley (15), which affects its district of wheels (5) or the wheels of wheelsets (6).the number of burdensome rollers (15) is two, and each pulley (15) on the one wheel (5) of the wheelset, and thanks zu00e1stavbovu00fdm dimensions and construction is the calibration condition umu00edstitelnu00fd beneath the vehicle (16) in which is located a wheel (5) or (6), for the calibration of the wheelset, loading.transverse position to the pulley (15) or pulleys and focal points can change the loading reduction frame (20) of different widths for different separations of rails, while the calibration condition is mobile.
