Multistage mixing type energy consuming and shock absorbing device

Abstract

The invention discloses a multistage mixing type energy consuming and shock absorbing device. The multistage mixing type energy consuming and shock absorbing device comprises mass blocks, a pendulum box and an outer box body. The mass blocks are installed on the outer box body and are connected with the outer box body through vertically-arranged springs, the pendulum box is fixed to the bottom of the mass blocks through a connecting device, and the pendulum box is connected with the outer box body through horizontally-arranged springs; a spring is hung in the pendulum box, and a metal pendulum ball is connected with the bottom of the spring; permanent strong magnet blocks with opposite magnetic poles are fixed to the top and the bottom of the pendulum box, magnetic induction line is cut when the metal pendulum ball swings in the space, and thus electrical eddy current is formed in the metal pendulum ball, and an electromagnetic field is formed by the induced electrical eddy current to impede relative motion of the pendulum ball; and thus mechanical energy is converted to electric energy to be consumed; the inner part of the outer box body is filled with water to form a TLD device, the TLD device can shake under the effect of external force, and inertial force opposite to the structure is generated, meanwhile water can collide with the pendulum box and the outer box body to consume the energy of structural vibration, and multistage and effective energy consumption and shock adsorption are achieved.

Description

technical field [0001] The invention relates to the field of structural engineering vibration control, in particular to a method for reducing the vibration response of towering structures under earthquake and wind loads, in particular to a multi-stage hybrid energy consumption vibration reduction device. Background technique [0002] In recent years, with the development of the national economy and the advancement of urbanization, the demand for various high-rise structures (wind turbines, transmission tower-line systems, communication towers, chimneys, etc.) is increasing in the process of infrastructure construction. However, this structure is characterized by high height, strong flexibility, small damping, and light structure. It is very sensitive to dynamic loads such as earthquake loads and wind loads, and the vibration is very obvious. Once it fails or is damaged, it will cause huge economic losses to the society. Strong vibration often makes the structure unable to ma...

Problems solved by technology

Passive control has a complex structure, high cost, and takes up a lot of space. After the installation is completed, the configuration of the mass block and the stiffness of the spring are inconvenient to adjust. The active control effect is remarkable, but it requires external energy and the controller is equipped with high technology, so it is difficult to apply.
