报告摘要:
Based on the team’s research efforts over the years, an in-situ structural health monitoring (SHM) technique taking advantage of guided elastic waves has been developed, and deployed via an online diagnosis system. The technique and the system were recently installed on China’s latest high-speed train model (CRH380CL) operated on Beijing−Shanghai High Speed Railway (BSHSR), the world’s longest high-speed line constructed in a single phase. The system incorporated modularized components including active sensor networks, wave generation, data acquisition, signal processing, data fusion, and results presentation. The sensor network, inspired by a concept of “decentralized standard sensing”, was integrated into bogie frames during train final assembly, to generate and acquire guided ultrasonic waves, from which a wide array of signal features were extracted. Mock-up damage affixed to the bogie was identified quantitatively, and visualized in images. This in-situ testing has demonstrated the feasibility, effectiveness, sensitivity, and reliability of the developed SHM technique and system in real-world applications.
