摘要

Purpose

This study proposes a novel Cable Rotating Mass System with Tuned Inerter Damper (CRMS-TID) to replace the traditional viscous damper (CRMS-VD) configuration. The aim is to achieve superior passive vibration control performance, including enhanced mitigation efficiency, broader frequency control, and greater energy dissipation, while maintaining lightweight design and facilitating straightforward field installation, without increasing total inertance.

Methods

The motion control equations of the CRMS-TID system are established. Closed-form optimal expressions are derived based on H_∞, H₂, and H₂/H_∞ optimization criteria. The performance of a dual-inerter-based CRMS-TID is evaluated under different external excitations and compared with that of the conventional CRMS-VD system, with particular attention to vibration mitigation, control force, energy dissipation, and required damping coefficients.

Results

Under comparable stiffness and the same inertance, CRMS-TID outperforms CRMS-VD in vibration mitigation, control force reduction, and energy dissipation, while providing broader frequency control for targeted modes. CRMS-TID requires damping coefficients less than 10% of those in CRMS-VD. Despite its lower damping coefficient, the dual-inerter configuration enhances damping effect, dissipating 10.7% to 13.1% more energy than CRMS-VD and far exceeding single-inerter configurations. The system achieves improved performance without additional inertance, supporting lightweight and cost-effective implementation.

Conclusion

The CRMS-TID system offers a feasible and effective alternative to CRMS-VD for passive vibration control in cable-braced structures. Its dual-inerter configuration enables superior control performance, higher energy dissipation, and broader frequency mitigation with ultra-low damping coefficients, while maintaining lightweight design and field installability.
