A Study for Establishing an Accurate Estimation Method of Axle Weights for In-motion Vehicles with High Velocity by Using Miniature Experimental Models

车轴称重系统测量行驶车辆的车轴重量。为了提高测量轴重的精度，研究了一种通过处理轴重系统的重量信号来估计轴重的方法。为了检验和提高所测轴重的准确性，研制了一种微型仪表车和微型轴重称重系统。并通过实验验证了微型模型的各项功能，获得了微型仪表车的运动数据和重量信号。利用得到的权重信号，验证了该方法能较好地估计权重信号中的振动分量。

Axle weighing system measures axle weights of in-motion vehicles. A method have been studied for estimating the axle weights by processing weight signals from the axle weighing system to improve the accuracy of the measured axle weights. In this study, to examine and improve the accuracy of the measured axle weights, a miniature instrumented vehicle and a miniature axle weighing system have been developed. Also each function of the miniature models is verified through the experiments to obtain motion data of the miniature instrumented vehicle and weight signals. By using the obtained weight signals, it has been examined that the method can estimate the vibration component in the weight signals adequately.
