摘　　要：针对轨道衡称重误差补偿不佳问题,提出不断轨称量轨式动态衡原理及轨道衡称重误差补偿方法。分析剪力称重波形图,确定传感器非线性特性,结合梯度训练法回归方程,构建误差补偿模型。计算轨道衡在稳定与倾斜状态下的受力,构造传感器输入输出拟合函数,进行误差逼近补偿。实验结果显示,补偿后误差最大减12.13 kg,倾角0°~35°内波动值控于0.7 kg以下,有效提升了补偿效果。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.
