摘要:

Suspended mass pendulum has the advantages such as definite mechanism, simple structure and superior damping effect, but the traditional simple pendulum is restricted by the deficiencies including difficulty of adjusting pendulum length and the lacking of the multiple modals tuning, so it has no engineering feasibility. In view of the above problems, the suspended mass pendulum system coupled with multiple tuned mass blocks and multi springs is proposed, and the system periods can be flexibly controlled by multiple additional springs and mass blocks, so the tuning vibration control of multi-mode shapes can be realized at the same time. The dynamic equation of the suspended double pendulum is presented, the dynamic analysis is carried out to obtain the frequency analytical solution, and the corresponding damping mechanism is formulated. On this basis, the dynamic equation of the building structure with suspended double pendulum is established. One uniform structure and one stiffness decreasing structure are selected as the controlled structures to study the damping effect of the simple pendulum and the double pendulum. The results show that the damping effect of the suspended double pendulum is much better than that of the suspended simple pendulum, and multiple modal tuned control is realized. In addition, the suspended double pendulum has more excellent robustness and practicability, so it is suitable for high-rise building structures. © 2019, Nanjing Univ. of Aeronautics an Astronautics.
