Abstract

This paper presents modal-based Looseness and damage detection for jointed frame structure. Specifically, we focus on localized flexibility properties that can be deduced from the experimentally determined global flexibility matrix. We present the underlying theory that can be viewed a generalized flexibility formulation in different generalized coordinates, viz., localized or substructural displacement-basis and element strain-basis. Then, the present methods are applied to detection of loosing part for the engine mount model made of four tubular members combined by bolts and damage detection for CFRP tubular member. The numerical and experimental results show that the present method is quite useful for detecting the loosing part and damage location of the joint frame structure.
