Application of Non-destructive Testing Digital Twin Technology in Wujiang Bridge
Taking the construction of health monitoring system for WuJiang Bridge,propose a non-destructive testing(NDT)method based on digital twin technology,combines three-dimensional modeling technology,sensor technology,finite element(FE)method,and surrogate model,the FE model can be regarded as a virtual sensor to reflect the performance of the bridge structure.Through the NDT method of digital twin technology,the structural performance of the entire bridge is comprehensively monitored,providing strong support.In addition,this method fully integrates the structural analysis ability of the FE model and the easy modeling and low cost characteristics of the proxy model,maintenance costs is reduced and the service life of the bridge is extended.
