Actividades de monitorización estructural sobre buques desarrolladas en la SGSN-CEHIPARmedios, objetivos y proyectos

Zusammenfassung

This paper shows the different research lines that are being developed in the field of structural health monitoring (SHM) at INTA’s Naval Directorate (SGSN). Structural Health Monitoring must be one of the technologies integrated into future ships to be able, among other things, to estimate the remaining life of the hull, detect damage, guarantee the safety of the ship or support during the design or certification process among others. Structural monitoring can allow the design of ships with more optimized and lightweight structures that reduce their environmental impact as well as being a key element in the development of autonomous ships. INTA has more than 20 years of experience in the field of SHM in aeronautical and space structures that it now intends to transfer and adapt to the naval requirements and applications of both real ships and scale models. From the point of view of the sensor, the SGSN has specialized in Fiber Bragg Grating Sensors (FBGS) and is studying the characterization of its response to complex load phenomena and low temperatures (cryogenics). From the point of view of data exploitation, work is being done on the reduction and simplification of massive sensor data using PCA (Principal Component Analysis) techniques.
