Abstract
|
|
|---|---|
| The wavelet transform and Lipschitz exponent perform well in detecting signal singularity. With the bridge crack damage modeled as rotational springs based on fracture mechanics, the de°ection time history of the beam under the moving load is determined with a numerical method. The continuous wavelet transformation (CWT) is applied to the de°ection of the beam to identify the location of the damage, and the Lipschitz exponent is used to evaluate the damage degree. The in°uence of di®erent damage degrees, multiple damage, di®erent sensor locations, load velocity and load magnitude are studied. Besides, the feasibility of this method is veri ?ed by a model experiment. | |
