Abstract

To improve the identification accuracy of the BWIM system on the orthotropic steel deck (OSD) and enhance its algorithm stability, this paper compared two different axle load calculation methods, including the parameter C algorithm and Moses algorithm. By conducting calibration tests on the actual bridge, two algorithms were adopted to identify the axle load of its vehicles. The identification results show that when the BWIM system is applied to OSD, the mean error value and standard deviation of the axle load identified by the parameter C algorithm are better than those of the traditional Moses algorithm. By utilizing the European standard COST 323 to evaluate the calibration results of the two algorithms, it is found that the accuracy level of the final evaluation results of the parameter C algorithm is relatively high, reaching C(15). Further analysis of the evaluation results reveals that the identification of the axle load of a single axle directly affects the accuracy evaluation of the BWIM system when the system is applied to OSD. Therefore, the key to improving the accuracy evaluation of the algorithm lies in enhancing the single axle identification accuracy.
