The subject of this thesis is Numerical Simulation of Gyroscopic Effects in Ansys. A natural
frequency analysis and a transient response analysis are performed in Ansys Classic for a sim-
ple rotor configuration. The results are verified with analytical solutions.

The structural response of a floating wind turbine is analyzed and the influence of gyroscopic
effects is examined. This is done by comparing two situations where in the first situation the
wind turbine is analyzed in parked condition and in the second situation in operational mode.

The gyroscopic effect introduces additional forces and vibrations in the tower of the wind tur-
bine. However, these forces are very small compared to forces generated by the wave motion of
the wind turbine. The tendencies observed in this thesis work correspond to previous research.
