Edgewise vibration suppression of multi-megawatt wind turbine blades using passive tuned mass dampers
Autor: Semyung Park, Matthew A. Lackner
Publikováno v: Wind Engineering. 45:1082-1100
The lack of aerodynamic damping of wind turbine blades in the edgewise direction causes larger dynamic responses and lowers the reliability. As blades become longer, edgewise fatigue loading increases rapidly. To mitigate the blade edgewise vibration

Multi-objective optimization of orthogonal TLCDs for reducing fatigue and extreme loads of a floating offshore wind turbine
Autor: Matthew A. Lackner, Semyung Park, Meghan Glade
Publikováno v: Engineering Structures. 209:110260
Floating offshore wind turbines have substantial potential to harness energy in deep-water locations, however, compared to fixed-bottom offshore wind turbines, they also have more complicated dynamic behavior that may lead to larger structural loads.

Application of the New IEC International Design Standard for Offshore Wind Turbines to a Reference Site in the Massachusetts Offshore Wind Energy Area
Autor: Semyung Park, James F. Manwell, Evan M. Gaertner, Matthew A. Lackner, Samuel Roach
Publikováno v: Journal of Physics: Conference Series. 1452:012038
The IEC 61400-3-1 standard for a fixed-bottom offshore wind turbine was applied through simulation of specified Design Load Cases. A metocean data set was assembled based on probability distributions of wind and wave data from a representative site i
