Low-damping tuning inerter damping device
The invention belongs to the technical field of low-frequency vibration control and provides a low-damping tuning inerter damping device aiming at the problems that an existing inerter damper is too high in damping ratio, unstable, low in vibration control efficiency and not suitable for large-scale engineering, possibility is provided for achieving the needed optimal damping ratio of a whole system, and then low-frequency resonance is efficiently controlled. Different from a traditional rigid supporting and transmission mode, the device adopts an economical, reliable and convenient flexible suspension supporting and transmission mode, and low frequency, stability and low damping of the system are achieved. The flexible supporting component and the rigid inerter device are in surrounding contact transmission, high damping caused by instability and high energy consumption due to friction and collision in a traditional inerter tuned mass damper is eliminated, and therefore it is guaranteed that a large inerter system achieves the stable low damping ratio, the conditions needed for achieving the optimal control effect are met, and the control effect of the large inerter system is improved. The method is directly applied to large-scale engineering structure resonance control.
本发明属于低频振动控制技术领域，针对现有惯容阻尼器阻尼比过高、不稳定、振动控制效率低、无法适用于大型工程的问题，提供了一种低阻尼调谐惯容阻尼装置，为整个系统实现所需的最优阻尼比提供可能，进而高效控制低频谐振。不同于传统刚性支撑和传动方式，该装置采用经济、可靠、便利的柔性悬吊支撑和传动方式，实现系统的低频率和稳定低阻尼。柔性支撑部件与刚性惯容装置环绕接触传动，消除了传统惯容调谐质量阻尼器中因摩擦、碰撞导致的不稳定高耗能带来的高阻尼，从而保证大型惯容系统实现稳定的低阻尼比，满足实现最优控制效果需要的条件，直接应用于大型工程结构谐振控制。
