Double tuned inertial system

Abstract

The invention relates to a double-tuned inertance system in the civil engineering and energy infrastructure field. The system comprises a first-grade collision friction type tuning mass unit, a second-grade tuning mass unit, a liquid inertance damping unit and an installation unit. In the invention, a double damping tuning mechanism is established to adjust a system frequency and carry out dampingcontrol, and the frequency bandwidth of the effective damping control of the damping system is increased. The two grade tuning mass units and the liquid inertance unit are used to store energy. The nonlinear collision of a collision friction block and a liquid inertance damping dissipation structure are used to vibrate energy. Based on the quality synergy effect of the liquid inertance unit, additional mass required for the first-grade collision friction type tuning mass unit is greatly reduced, and a light-weight tuning damping device is provided. In addition, the inertance unit effectivelycontrols the deformation of the entire first-grade collision friction type tuning mass unit, the installation space of the device is saved, the efficiency of the internal damping energy consumption of collision friction block damping is improved, and the system has a wide application prospect.

Description

technical field

[0001] The invention belongs to the technical field of energy consumption and vibration reduction of civil engineering structures, and in particular relates to a double-tuned inertial capacity system. Background technique

[0002] Energy dissipation and vibration reduction technology, by adding an energy dissipation and vibration reduction device at the part where the structure will move relative to each other, the device can generate a control force that resists the structural movement when the structure is forced to jointly bear the effects of earthquakes and wind vibrations, using its own The energy dissipation effect reduces the dynamic response of the structure itself, ensuring the functional requirements of the structure's safety, comfort and normal usability.

[0003] As a relatively mature nonlinear energy dissipation and vibration reduction device in this field, the collision friction block damper absorbs and dissipates the vibration energy of the co...
