Abstract

Aiming at the problem of limited vibration control range due to the mutual coupling of damping, inertance, and stiffness，a fluid-based inerter with meandering-tube layout is proposed. Based on the working mechanism of fluid-based inerters, a mathematical model for the damping of the meandering-tube is established using the analogy method between mechanical and hydraulic networks. Simulation verifies that independent damping adjustment of the tube can be achieved by adjusting key design parameters of the meandering tube while maintaining constant inertance and stiffness. Additionally, a prototype of the fluid-based inerter was developed and its mechanical properties were tested. The results indicate that the proposed meandering-tube design accomplish the physical decoupling of damping, inertance, and stiffness, thereby expanding the vibration control range of fluid-based inerters. This offers a new and practical approach to damping design for the development of similar fluid-based vibration damping equipment.
