摘要：

The problem of multi site damage precise localization, that is multi site damage coordinate estimation is addressed via the random vibration based stochastic Functional Model Based Method (FMBM). Damage detection and precise localization for pairs of damage locations on the wing of a lab scale Garteur skeleton structure is achieved based on the vibration response measured via a single accelerometer at a low and limited operational frequency bandwidth. The results of the study indicate excellent damage detection and remarkable localization of the considered multi site damage scenarios. (C) 2017 The Authors. Published by Elsevier Ltd.
