Low-frequency vibration suppression of raft-hull systems using lever-type vibration isolators with tunable negative stiffness

Key Points

• Vibration suppression was notably improved, achieving an optimal performance enhancement of 30%.
• Key metrics include a frequency range from 5 Hz to 20 Hz, demonstrating significant dampening capabilities.
• Assessment using lever-type vibration isolators with negative stiffness shows promising results in a controlled environment.
• This approach may lead to better stability in marine structures, suggesting further exploration in real-world settings.
