Metal shearing type energy dissipation device with displacement amplifying function

Abstract

The invention discloses a metal shearing type energy dissipation device with the displacement amplifying function. The metal shearing type energy dissipation device comprises a restraining box body, a damping core plate and adjusting plate sets. An opening is formed in the top of the restraining box body. A first connecting plate is arranged at the bottom of the restraining box body. The damping core plate is arranged in the restraining box body, and the first end of the damping core plate is connected with the first connecting plate. The first ends of the adjusting plate sets penetrate the opening and are connected with the second end of the damping core plate through first pivot shafts in a pivoted manner. The second ends of the adjusting plate sets are connected with a second connecting plate located outside the restraining box body through second pivot shafts in a pivoted manner. Supporting point shaft holes close to the second pivot shafts is formed in the adjusting plate sets. Supporting point shafts are inserted into the supporting point shaft holes. The two ends of each supporting point shaft are arranged on the side wall of the restraining box body. According to the metal shearing type energy dissipation device with the displacement amplifying function, when the second connecting plate generates horizontal deformation, the adjusting plate sets are driven to rotate around the corresponding supporting point shafts, reversed deformation is applied to the damping core plate, deformation of the upper end of the damping core plate is larger than horizontal deformation generated on the second connecting plate, the damping core plate is accelerated to enter the plastic state, and the energy-dissipating capacity of the damping core plate is brought into full play, so that the structural shock resistance is improved.

Description

technical field [0001] The invention relates to the design field of metal energy dissipators, in particular to a displacement-amplified metal shear energy dissipator. Background technique [0002] Installing appropriate energy-dissipating components in the building structure can enhance the seismic performance of the building structure. The metal energy-dissipating device is an energy-dissipating shock-absorbing device with superior energy-dissipating performance and simple structure. It is easy to manufacture, low in cost and easy to replace. Metal energy dissipators can be used in combination with shock-isolation bearings or vibration-isolation systems as energy-dissipating units or limiting devices, and can be used alone in building structures as energy-dissipating devices to provide additional damping and stiffness, so they have a wide range of applications. application prospects. [0003] As a passive control device, metal dampers have been widely used in the vibration...
