title = "Modal analysis of a large direct-drive off-shore wind turbine generator rotor",
abstract = "In permanent magnet direct-drive wind turbines, structural flexibility of the generator structure recently came into focus as an potential issue when reducing weight of the nacelle. The increased flexibility makes a dynamic analysis of the structure necessary to ensure that it does not compromise the functionality. This paper conducts an experimental modal analysis of a direct-drive generator rotor. The modal analysis was done using in-situ measurements of the rotor. Various excitation methods, including operational modal analysis and hammering tests, were tried and compared to find the most suited one for this application.",
