Abstract EN
Bolted joint is widely used in mechanical and architectural structures, such as machine tools, industrial robots, transport machines, power plants, aviation stiffened plate, bridges, and steel towers.
The bolt loosening induced by flight load and environment factor can cause joint failure leading to a disastrous accident.
Hence, structural health monitoring is critical for the bolted joint detection.
In order to realize a real-time and convenient monitoring and satisfy the requirement of advanced maintenance of the structure, this paper proposes an intelligent bolted joint failure monitoring approach using a developed decision fusion system integrated with Lamb wave propagation based actuator-sensor monitoring method.
Firstly, the basic knowledge of decision fusion and classifier selection techniques is briefly introduced.
Then, a developed decision fusion system is presented.
Finally, three fusion algorithms, which consist of majority voting, Bayesian belief, and multiagent method, are adopted for comparison in a real-world monitoring experiment for the large aviation aluminum plate.
Based on the results shown in the experiment, a big potential in real-time application is presented that the method can accurately and rapidly identify the bolt loosening by analyzing the acquired strain signal using proposed decision fusion system.
