Design of Nacelle and Rotor Hub for NOWITECH 10MW Reference Turbine
MetadataVis full innførsel
Wind turbine development has been formidable in the last years. One of NOWITECH's goals are to do research on large offshore wind turbines. A bed plate and hub for the NOWITECH 10MW reference turbine has been analyzed, according to IEC 61400. The work is based on Ebbe Smith's thesis about bed plate design, and Mohammad Akram Khan's thesis about rotor shaft and rotor hub design. A completely new bed plate has been designed, and analyzed with more correct boundary conditions including a yaw bearing with contact surfaces and bolt connections between flanges. The hub received minor modifications, and is analyzed with a bolt connection and pitch bearings.The mass of the new bed plate is 99.6 tons, and a has peak stress of 217.5MPa which is justified in discussion. The peak stress in the hub is 126MPa.
