Abstract
In order to capture more energy, wind turbines are rapidly growing in height and rotor size. This growth increases the likelihood that soil structure interaction effects may influence the structural dynamic response. Current 3 MW turbines tower over the landscape with an 80 meter hub height and a 90 meter rotor diameter. This paper models a full soil structure system for the National Renewable Energy Laboratory onshore 5 MW reference wind turbine with a hub height of 90 meter and a 126 meter rotor diameter. A detailed finite element model of the turbine is created, including a full three dimensional soil mesh to study the influence of soil structure interaction on the dynamic properties and response. The tower moment and shear demand is presented after the turbine is modeled on 3 - 15 meter thick soil profiles of varying stiffness and subjected to a 1994 Northridge Earthquake record. The investigation provides valuable insight into the extent that soil structure interaction influences the behavior of this new generation of large wind turbines.
