Damage identification of structures using experimental modal analysis and continuous wavelet transform
Abstract: Modal analysis is a powerful technique for understanding the behavior and performance of structures. Modal analysis can be conducted via artificial excitation, e.g. shaker or instrument hammer excitation. Input force and output responses are measured. That is normally referred to as experimental modal analysis (EMA). EMA consists of three steps: data acquisition, system identificatio...
متن کاملFault Detection of Plain Circular Knitted Fabrics Using Wavelet Transform
Quality control of textile products is an important stage in textile industries. To this end, the conventional method in fault detection is human inspection. In the present work, Wavelet transform was applied on images of simple circular knitted fabrics to diagnose five regular defects. The results showed that the method applied was accurate and fast in addition to being capable of determining ...

متن کاملCrack Detection of a Beam Using the Wavelet Transform
The dynamic behaviour of a structure changes when it is subject to damage such as cracking. Recently research has been directed at employing conventional Modal Analysis techniques to investigate this change in simple structures and to study the dependency on the location and size of a crack. The use of the modeshapes to characterise the dynamic behaviour of the structure would require several a...
