| dc.description.abstract | Objective of this thesis is to find optimal sensor placements regarding vibration-based damage by utilizing modal parameters of a structure. The location of sensors is crucial for correct identification of the mode shapes of complicated mechanical structures. In this study, a specific model of a 100m wind tower was analyzed to determine the optimal sensor placement algorithm for vibration-based damage detection. The vibration-based damage detection was conducted to the system and damage was localized using a mode shape-based damage identification technique. The optimal sensor placements were obtained by minimization of weighted off-diagonal elements, QR decomposition, the genetic algorithm with maximum errorand the genetic algorithm with weighted off-diagonal criteria. Among these three algorithms, the genetic algorithm with weighted off-diagonal criteria yielded the most effective sensor placements for the highest damage detection accuracy. | |
