Method and system for dynamic identification of vehicle axle load based on loading of arch bridge hanger force influence surface

Abstract

A method for dynamically identifying the axle load of a vehicle based on loading on an arch bridge hanger force influence surface, comprising: extracting girder type and structural parameter control information; extracting the theoretical hanger force influence surface control information of an arch bridge hanger force measurement point; The rod force influence line result corrects the influence surface of the boom force; sets the trigger recognition vehicle axle load recognition corresponding to the arch bridge boom force threshold; the vehicle axle load recognition system recognizes the vehicle axle load through the arch bridge. The present invention integrates comprehensive applications such as big data, machine learning, deep learning, safety monitoring, automatic control, computer technology, precision sensing technology, etc., and realizes based on the extraction of structural characteristic parameters and real-time structural response, based on structural dynamic loads. The arch bridge hanger force is used as the identification parameter to reversely identify the vehicle load of the arch bridge, realizing a new generation of intelligent monitoring products with intelligent computing as the core, and an identification system and method featuring self-sensing, self-adaptation, self-learning and self-decision-making.

Description

technical field [0001] The invention relates to the technical field of vehicle axle load identification, in particular to a method and system for dynamically identifying vehicle axle loads based on surface loading influenced by force of an arch bridge suspender. Background technique [0002] The identification of vehicle loads on existing bridges is generally divided into dynamic weighing methods and static weighing methods. Among them, static weighing methods are the most widely used, and static weighing methods generally require special scales to detect overweight vehicles, which are costly and require Stopping the vehicle and weighing it will easily cause traffic jams for bridges with large traffic flows. Using this weighing system often becomes a traffic jam point. Moreover, static weighing can only monitor the total weight, but cannot obtain the weight distribution of each axle of the vehicle. [0003] Another dynamic weighing method based on the pavement uses the equ...

Using this weighing system often becomes a traffic jam point

Moreover, static weighing can only monitor the total weight, but cannot obtain the weight distribution of each axle of the vehicle

[0003] Another dynamic weighing method based on the pavement uses the equipment laid on the bridge deck to weigh the vehicles on the bridge deck. This method causes a certain degree of damage to the road surface, and the traffic flow is easy to cause damage to the equipment, which limits the use of the equipment. Useful period
