Abstract: (110 Views)
The damage and failure in engineering structures, especially offshore structures, and hull of ship structures, causes economic losses, human disasters, and environmental problems. Therefore, diagnosing and predicting the occurrence of failure in these structures is vital. In this situation, engineers have introduced the use of structural health monitoring operations as a suitable way to prevent the collapse of the structures. Implementing structural health monitoring operations includes several steps. One of the most important and challenging steps is the placement of sensors on the structure. There are several theoretical methods to find the best positions for placing the sensor on a structure. In this paper, some methods were implemented on the model of fast ship structure and compared the results. For this purpose, first, the vibrational characteristics of the structural model of a ship were extracted by performing modal analysis, and the best-proposed positions for placing the sensors according to different methods obtained. The results show that the "Effective Independent" method is more effective than other methods. Its proposed positions are better distributed throughout the ship's structure, while the proposed positions of other methods in several small areas of the ship structure are concentrated.
Keywords: Sensor placement, Structural health monitoring, Ship structure, Mode Shape, Effective Independent Method
