Frequency island effect and the vibration suppression performance of a bistable nonlinear energy sink-piezoelectric system coupled with the main structure

Key Points

• Vibration suppression performance is enhanced with a bistable nonlinear energy sink system, indicating more effective energy dissipation.
• The system shows significant performance improvements, with coupling to the main structure providing key enhancements in vibration control.
• Assessment using a coupled system framework demonstrates the vibrational impacts on structural integrity, emphasizing the role of energy sinks.
• The results may highlight innovative approaches to reduce vibrations in civil structures, but further validation is needed.
