| Summary: | A model for quick load analysis, QuLA, of an offshore wind
turbine substructure is presented. The aerodynamic rotor loads and damping
are pre-computed for a land-based configuration. The dynamic structural
response is represented by the first global fore-aft mode only and is
computed in the frequency domain with phases using the equation of motion.
The model is compared to the state-of-the-art aeroelastic code Flex5. Both
lifetime fatigue and extreme loads are considered in the comparison. In
general there is good agreement between the two models. Some deviations for
the sectional forces are explained in terms of the model simplifications. The
differences in the sectional moments are found to be within 10 % for the
fatigue load case and 10 % for the extreme load condition. |
