The system comprises a tuning spring unit, an inertance unit, a collision friction damping unit and an installation unit. The inertance unit is taken as an energy absorption and energy consumption synergy mechanism, one end is connected tothe side portion of the installation unit and the other end is connected to the collision friction damping unit. The inertance unit and the collision friction damping unit are slidably arranged on the bottom of the installation unit through the respective bottom. Simultaneously, the two ends of the tuning spring unit are connected to the side portion of the installation unit and the collision friction damping unit. In the invention, multiple vibration absorption and energy dissipation mechanisms are established, the quality synergy effect of the inertance system is fully used and additional physical mass required for the collision friction damping unit is effectively reduced, and simultaneously, the deformation of the entire collision friction damping unit can be effectively controlled and the efficiency of the internal damping energy consumption of collision friction damping is further improved.

AI Technical Summary

Problems solved by technology

However, this type of vibration damping device often has problems such as high collision noise of the collision friction ball, large mass of the additional collision friction ball, insufficient collision of the collision friction ball, and low energy consumption efficiency of the vibration reduction device.

If the overall deformation of the collision friction ball unit relative to the controlled structure is large, it will take up more building interior space

Under strong external effects such as earthquakes, the large additional mass of the collision friction damper not only cannot effectively reduce the dynamic response of the structure under earthquakes, but also has certain safety hazards
