Low-frequency tuned mass damping device
The invention belongs to the field of low-frequency vibration control, and provides a low-frequency tuned mass damping device. The spring and the functional element with sufficient strength and local overall rigidity close to zero are combined for use to share the gravity of the vibrator together, so that the problems of overlarge spring deformation and insufficient controlled structure space of a traditional tuned mass damping device under a low-frequency condition are solved. The functional element provides stable tension during vibration, so that the vibrator is larger in mass, and the spring is shorter and lighter. And compared with an inerter device, the inertia force is larger, the required system damping is higher, and the vibration control efficiency is higher. Functional elements are bilaterally and symmetrically tensioned, and high-strength thin ropes and large-diameter turntables are introduced, so that the friction energy consumption can be greatly reduced, the system damping is ensured to meet optimization conditions, and the vibration control efficiency is ensured. The method has remarkable advantages in the field of low-frequency vibration control, and can be used for vertical low-frequency vibration control of various large structures.
本发明属于低频振动控制领域，提供了一种低频调谐质量阻尼装置。通过将弹簧与具有足够强度和局部总体刚度接近于零的功能元件组合使用，共同分担振子的重力，避免了传统调谐质量阻尼装置在低频条件下弹簧变形量过大、被控结构空间不足的问题。功能元件在振动中提供稳定拉力，使得振子质量更大、弹簧更短、更轻。相对惯容装置惯性力更大，需要系统阻尼更高，振动控制效率更高。功能元件左右对称张拉、高强细绳索和大直径转盘的引入，可以大幅降低摩擦耗能，确保系统阻尼满足优化条件，保证振动控制效率。本发明在低频振动控制领域具有显著优势，可用于多种大型结构竖向低频振动控制。
