MAG2C-Pont Tabarly
Participant : Ivan Guéguen.
-
Partners: IFSTTAR, CSTB, Nantes Métropole, Université de Nantes
-
Abstract: The project deals with the instrumentation of the Tabarly Bridge.
The instrumentation auscultates globally the structure, a structural defect in a given location changes its modal parameters and thus the vibration behavior. Then it can be detected on any part of the structure with an accelerometer. These measures coupled with a wireless data transmission system type or wifi 3g will allow remote monitoring of the evolution of the structure. And where appropriate, to deploy when necessary, for maintenance. The different objectives are
The instrument proposed is based on an accelerometer-based distributed network on the structure. This assembly is connected to a data acquisition system and a modem 3g for continuous measurements and remotely. The vibration will be collectable on the internet.
Project wind turbine in St Hilaire de Chaleon
Participant : Ivan Guéguen.
-
Abstract: The project deals with the instrumentation of the wind turbine.
The aim is firstly, to instrument the foundation before casting with continuous optical fibers, optical strain gauges, temperature sensors and accelerometers for a detailed analysis of the behavior of the founding quasi static and dynamic. In a second time to instrument the mast with accelerometers to the study by SSI under ambient vibration method. All of which should help better understand the global behavior of the structure.
Collaboration with GEM
Participants : Laurent Mevel, Michael Doehler, Md Delwar Hossain Bhuyan.
Md Delwar Hossain Bhuyan has started a PhD on Damage localisation on offshore platforms, The thesis is co-directed by L. Mevel and F. Schoefs from GEM, Nantes, with supervision shared with M. Doehler and Y. Lecieux from GEM. It is funded by the Brittany region for 3 years.
