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 liquid-tuned inertial capacity system. Background technique [0002] The energy dissipation vibration reduction technology is a technology to reduce the vibration response of the structure by installing energy dissipation vibration reduction devices at the positions where the structure deforms greatly during the vibration process. The energy-dissipating vibration-damping device can use its own characteristics, such as hysteresis deformation and friction, to consume a large amount of input energy and suppress the dynamic response of the main structure when the structure is subjected to strong vibrations such as earthquakes or strong winds, which not only ensures the safety of the structure It improves its reliability, and at the same time, it can meet the requirements of the user's comfort and the nor...

AI Technical Summary

Problems solved by technology

However, the tuned liquid damper can only suppress the vibration of the frequency close to the natural frequency of the tuned liquid, the controlled frequency band is narrow, and the energy consumption mechanism of the tuned liquid is single and the efficiency is not high.

In addition, the device occupies a large space, and when subjected to relatively large vibrations, the deformation of the device is relatively large, which increases the difficulty of device installation
