Abstract

The invention discloses a two-way inertia speed type damper. The two-way inertia speed type damper comprises a sleeve part, a forward inertia brake disc part and a reverse inertia brake disc part, twogroups of one-way transmission parts are arranged on a screw rod part at intervals, the one-way transmission parts are respectively connected with the forward inertia brake disc part and the reverseinertia brake disc part, the transmission directions of the two groups of one-way transmission parts are opposite, and a friction damping part is arranged in the sleeve part. The vibration force effect is sensed through the screw rod part, when the screw rod part rotates forwards, the forward inertia brake disc part is driven to rotate forwards through the one-way transmission parts, on the contrary, the reverse inertia brake disc part is driven to rotate reversely, linear reciprocating motion of the damper is converted into two-way accelerated motion of the forward inertia brake disc part andthe reverse inertia brake disc part, and then the two-way accelerated motion is converted into heat energy through the friction damping part at the end part of the inertia brake disc part, so that the problems of stress concentration, breakage and the like of the screw rod part due to change of the rotating direction of the screw rod part under the action of external force are solved.

Description

technical field [0001] The invention relates to the technical field of structure damping, in particular to a two-way inertia velocity damper. Background technique [0002] The damper can effectively reduce the vibration response of the structure and greatly improve the seismic performance of the structure. However, the energy consumption of traditional dampers is not efficient, the energy conversion rate is low, and they cannot cope with the input of large earthquakes. In severe cases, the dampers may fail. Traditional dampers can no longer meet the performance requirements of modern structural vibration control. Contents of the invention [0003] The purpose of the present invention is to solve at least one of the technical problems in the prior art, and provide a two-way inertia velocity damper, which can exert better anti-seismic performance. [0004] According to the embodiment of the first aspect of the present invention, a two-way inertial speed damper is provided, ...
