Dynamics of bistable nonlinear energy sinks and their application in monopile offshore wind turbines

Key Points

• Bistable nonlinear energy sinks effectively reduce vibrations, improving stability in offshore wind turbines.
• Significant reductions in peak vibration amplitude of up to 45% were observed during testing.
• Analysis involved numerical simulations and experimental setups to assess system performance under dynamic loading conditions.
• Improved energy absorption could enhance the operational lifespan of offshore wind turbine structures.
