Statistical Estimation of Perspective Damage Index for Vibration-Based Structural Health Monitoring

Journal of Physics: Conference Series 2019
Vitālijs Pavelko, Aleksandrs Nevskis

Statistical analysis of CCD (correlation coefficient deviation) index for the structural damage detection by vibration-based method was performed. Statistic data set was collected in a full-scale test of a large aircraft component. After special pre-processing the most informative narrow frequency band was selected for obtaining the statistic set of CCD between the frequency response functions of intact and pseudo-damaged states of a structure. The two-sample Kolmogorov-Smirnov hypothesis test was used for estimation of a pseudo-damage effect. The stable response of CCD index to a small damage in large-size structure was demonstrated.
