Problems solved by technology

In addition, the inventors found that in the collision energy dissipation technology, the collision gap has a great influence on the energy dissipation effect, but most of the collision energy dissipation technologies currently used are fixed collision gaps, and it is impossible to adjust the collision according to the different degrees of vibration response of the structure. clearance, which reduces the effective utilization of the collision energy-dissipating device

Abstract

The invention provides a multistage self-adaptive composite inertial-capacitance vibration damping device, method and civil engineering structure. The multistage self-adaptive composite inertial-capacitance vibration damping device comprises a mass body, wherein the mass body comprises a telescopic box body capable of moving in the Y direction, a plurality of telescopic plates which are placed in the Y direction and can move in the X direction are arranged in the telescopic box body, the telescopic plates are connected through linkage springs, and the telescopic plate on the outermost side is connected with a first-stage guide rail through a tuning spring, so that self-adaptive collision of collision balls between the telescopic plates in the X direction is realized; a magnetorheological hydraulic energy dissipation mechanism comprises an energy dissipation box, wherein the energy dissipation box is provided with a multistage sliding frame and a piston, the energy dissipation box is fully filled with magnetorheological fluid, the piston can slide along a rack on the inner wall of the energy dissipation box, and excitation coils are arranged at the two ends of the energy dissipation box; a transmission mechanism comprises a transmission plate, wherein the bottom of the transmission plate is fixed on the rack, and the transmission plate is connected to the inner side wall of a working box through a reset spring; and a displacement sensor is further installed on the transmission plate, is used for monitoring the displacement of the transmission plate, and is connected with the excitation coils through an electromagnetic control circuit.

Description

technical field [0001] The invention belongs to the field of vibration control of towering and large-span structures, and in particular relates to a multi-stage self-adaptive compound inertial vibration damping device, method and structure. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the development of high-rise and long-span structures towards diversified functions and complex structures, the vibration of structures under environmental loads is becoming more and more serious. Unfavorable vibrations will affect the performance and life of structures, and vibration reduction control measures can effectively solve the problem. Safety issues during the entire life of engineering structures to reduce the impact of disasters. Among them, the dynamic vibration absorption type vibration reduction device achieves the purpose of dynamic v...
