基于桥梁挠度的重载车辆荷载识别方法研究
Research on Heavy Vehicle Load Identification Method Based on Bridge Deflection
摘要
Abstract
Based on a bridge project of Ningbo City,Zhejiang Province,a heavy vehicle load identification method was proposed based on bi-directional long short-term memory network(BiLSTM).The time-dependent features of structural dynamic deflection were learned and extracted and the mapping relationship between vehicle weight and structural dynamic deflection was constructed to realize the inversion of heavy vehicle loading parameters.The pro-posed method is verified to have good robustness and generalization performance.The vehicle weight recognition ac-curacy can reach up to 91％and the anti-interference ability for multi-vehicle driving is stronger.The relevant con-clusions can provide reference for load identification of similar heavy vehicles.关键词
