Analysis of the error mechanism of non-rail weighing scale and improvement of error compensation method
Aiming at the problem of poor weighing error compensation of track balance,the principle of dynamic balance and the method of weighing error compensation were proposed.The shear weighing waveform map was analyzed,the nonlinear characteristics of the sensor were determined,and the error compensation model was constructed by combining the regression equation of gradient training method.The force of the rail scale in the sta-ble and inclined states was calculated,and the sensor input and output fitting function was constructed to compen-sate for the error approximation.The experimental results showed that the maximum error after compensation was re-duced by 12.13 kg,and the fluctuation value within the inclination angle of 0°~35°was controlled below 0.7 kg,which effectively improves the compensation effect.
