Abstract

The invention belongs to the technical field of bridge shock absorption, and particularly relates to a damper switching device and a method for simulating damper switching. A switching device for a damper includes a support table; a locking piece is installed on the support table; the locking piece has an opening, and an installation area for installing a lead screw in a ball screw damper is formed in the opening; a first elastic The support piece is connected with the locking piece, and the first elastic support piece can make the area of ​​the installation area decrease; the limit piece, one end of the limit piece protrudes into the opening, and under the force, the limit piece The second elastic support piece is connected to the limiting piece, and the second elastic support piece can prevent the limiting piece from being away from the mounting region. The switching device can automatically switch from the ball screw damper to the mild steel damper according to the magnitude of the vibration generated by the bridge and other vibrating structures, so as to maximize the advantages of the combined shock absorption system.

Description

technical field [0001] The invention belongs to the technical field of bridge shock absorption, and particularly relates to a damper switching device and a method for simulating damper switching. Background technique [0002] The ball screw damper, that is, the speed damper, its energy dissipation capacity is related to the speed, the greater the deformation speed, the greater the damping force. Ball screw damper is a new type of damping device that has been widely used in structural engineering vibration reduction in recent years. It converts the linear displacement between two points on the structure into rotational displacement through the ball screw, and drives the rotating mass block to rotate, thereby improving the structure. The inertial mass of the structure can be accelerated to consume the vibration energy of the structure through the eddy current damping device. [0003] Mild steel damper, namely displacement damper, its energy dissipation capacity is related to ...
