Turbulence consideration in wind turbine design and its effect on main shaft motion and blade root strain
MetadataShow full item record
This PhD research investigated the influence of turbulence effects on the vibration behaviour of wind turbines. A small laboratory scale wind turbine test facility was developed with special purpose instrumentation and sensors. Experimental investigations of the vibration behaviour of the turbine demonstrated the complexity of the displacements of the main rotor shaft and the strain at the roots of the rotor blade. This research will assist in the ongoing development of improved failure detection mechanisms.

(2016)The purpose of this research is to develop a meanline simulation model that provides a good starting point for the detail design of radial inflow turbine stages and then demonstrate the application of the model to the ...
Using multiple tuned mass dampers to control offshore wind turbine vibrations under multiple hazardsZuo, H.; Bi, K.; Hao, Hong (2017)© 2017 Elsevier LtdOffshore wind turbines can be built larger and lighter than they used to be due to the application of new materials. These large and flexible structures are vulnerable to external vibration sources such ...
