- The natural frequency analysis of four analytical models of a home wind turbine is presented in this paper. These models are: the rotor of a generator without housing, the rotor of a generator with housing and a stator, the rotor of a wind turbine, and the entire assembly of the wind turbine. By comparison of the received results of these models, evaluation of the variation in natural frequencies was performed. Additionally, interaction of the natural frequencies of the models with excitations was investigated. Moreover, various forms of vibrations, such as bending and torsional mode of the wind turbine rotor, rotor generator and blades, were found. Simplified analytical calculations for evaluation of the bearing stiffness applied to the vibration models were also carried out. The natural frequency analysis was performed in the analytical environment of the Siemens NX software based on NX Advanced module by the use of NASTRAN solver.
