Analysis of a Two-Bladed, Teetering-Hub Turbine Using the ADAMS(R) Software

    Research output: NRELTechnical Report


    A major goal of the federal wind energy program is the rapid development and validation of structural models to determine loads and reponse for a wide variety of different wind turbine configurations operating under extreme conditions. Such codes are crucial to the successful design of future advanced wind turbines. In cooperation with R. Lynette & Associates the Wind Technology Division at NRELhas developed a full system dynamics model of the AWT-26 P1 machine, using the Automatic Dynamic Analysis of Mechanical Systems (ADAMS) software from Mechanical Dynamics, Inc. In this paper, we show validation of sub-models by comparisons with modal test data. We describe the most important system modes involved in this structure and demonstrate how the ADAMS model can be used to tune thestructure to avoid interactions. We also identify questions that remain unanswered by ADAMS in modeling this turbine and recommend future directions that DOE code development activities should take.
