Three-dimensional vibrations of wind turbines
Abstract In this paper authors consider three-dimensional vibrations of a wind energy farms (WEF) of tower type VTR 50 Arctic. Low-frequency vibration of a WEF composed of a tower and rotor is considered in the out of balance condition. The method of analysis is based on the theory of mechanical osc...

| Summary: | Abstract In this paper authors consider three-dimensional vibrations of a wind energy farms (WEF) of tower type VTR 50 Arctic. Low-frequency vibration of a WEF composed of a tower and rotor is considered in the out of balance condition. The method of analysis is based on the theory of mechanical oscillations and the theory of elastic shafts. We consider the tower as a shaft and the rotor as a rigid body. Using the Lagrange’s equations for elastic structures in combination with computer simulation provides for the novelty and efficiency of the suggested method. The unique nonlinear equation is deduced and solved using the Wolfram Mathematica. |
