摘要：

This paper investigates the sensitivity of the natural frequency of a support structure of an offshore wind turbine to parameter variation and variation in models for pile foundations. The predicted natural frequencies are compared with measurements for several wind turbines in two wind farms in the Dutch 'inland sea' IJsselmeer. To interpret the results, the mode shapes of the free vibration and the distribution of maximum potential- and kinetic energy are analysed. Based on the analysis recommendations are given for foundation models to be applied in the design process.
