Abstract

The invention discloses a one-way self-resetting adjustable friction energy consumption damper, which comprises a friction sleeve, a friction damping part, an elastic body, a fixed end, and an end cover; and discloses a one-way self-resetting adjustable friction energy consumption damper The use method of the device is used for one-way reset and for adjusting friction. The one-way self-resetting adjustable friction energy dissipation damper proposed by the present invention uses the elastic body at one end of the friction sleeve to sense the displacement response of the controlled structure, and further changes the positive relationship between the friction unit and the inner wall of the friction sleeve by squeezing the friction unit. Pressure, to automatically adjust the size of the sliding friction force, which can meet the vibration reduction requirements of strong vibration and weak vibration of the structure at the same time; at the same time, the self-resetting adjustable friction damper of the present invention has a self-resetting function, which can be reused many times to save post-disaster reinforcement The time and economic cost of repair facilitates the rapid restoration of the function of the structure.

Description

technical field [0001] The invention relates to a one-way self-resetting adjustable frictional energy-dissipating damper and a using method thereof, which belong to the technical field of shock absorption. Background technique [0002] The friction damper is a damper with stable performance and strong energy dissipation capacity. It can convert the energy input into the building structure into heat energy through sliding friction to protect the main structure. It mainly uses the friction between metal and metal Or the friction between metal and non-metal creates damping. The current common friction damper, its friction surface positive pressure and friction coefficient can not be changed by itself, that is, the sliding friction remains basically unchanged. The most critical issue in the engineering application of this kind of constant friction friction damper is how to determine the appropriate sliding friction. On the other hand, the friction damper does not have a self-r...
