Abstract

Abstract:

The mode jumping phenomenon with the presence of damage in airship framework structure made traditional damage detection methods by matching structural dynamic parameters before and after damage failed. Hence, three dynamic methods were developed for damage detection only using global vibration response after damage. Modal parameters of structures were obtained through modal analysis method, and then three damage detection methods named mode shape curvature, uniform load surface curvature and virtual axial strain were proposed. New damage indicators were defined and the damaged members were localized by local peaks of damage indicators. An example was given with a typical large-scale tri-angular carbon fiber reinforced polymer composite space truss structure. It was widely used for semi-rigidity airship framework structure. The whole damage detection processes were simulated combined with finite element method and self-defined MATLAB program, and the influence factors include damage types, damage locations, damage severities, noise levels, etc. An experimental testing was conducted to verify the proposed damage detection methods. All results show that the proposed damage indicators are sensitive to damage and capable of identifying and locating single and multiple damaged members under environmental noise condition. The proposed methods based on structural global vibration thus could be used for real-time structural health monitoring system for airship framework in the future.

Key words: damage detection, damage indicator, airship framework, flexibility matrix, uniform load surface
