Abstract

The invention provides a self-adaptive viscous damper with a self-resetting function, and belongs to the technical field of structure damping. The self-adaptive viscous damper comprises a damper cylinder body, a plug-in type storage battery, a speed sensor, a dynamic controller and an electric proportional servo valve, wherein the plug-in type storage battery is used for providing voltage for thedynamic controller, the dynamic controller receives a speed signal from the speed sensor, then converts the speed signal into a voltage signal, and then transmits the voltage signal to the electric proportional servo valve, and damping force output by the damper cylinder body is controlled through the electric proportional servo valve. According to the provided novel viscous damper, a double-cylinder design is adopted, when an integral piston composed of a movable piston and a piston and shaft integrated part moves in a main cylinder in a reciprocating mode, the effect of parallel work of twodampers is achieved; and the effective flowing-through sectional area of a viscous fluid in a flow guide pipe is adjusted in real time, so that the flow of the viscous fluid in the flow guide pipe ischanged, and then the magnitude of damping is adaptively adjusted in real time.

Description

technical field [0001] The invention belongs to the technical field of structural damping, and in particular relates to an adaptive viscous damper with a self-resetting function. Background technique [0002] Viscous damper is a speed-dependent damper, which was first used in machinery, military industry, aviation and other fields to control the vibration and shock of equipment. With the continuous advancement of technology, viscous dampers are gradually being extended to civil projects such as building structures and bridges to dissipate the energy input to structures such as earthquake loads and wind loads. The viscous damper mainly includes several technical indicators such as damping coefficient, damping index, and maximum damping force. The damping coefficient of the conventional viscous damper is a fixed value, which cannot meet the needs of different damping forces under different working conditions in actual use. The damping force is small. In order to ensure suffic...
