Abstract

The invention discloses a built-in compartment type particle inertial-capacitance damper. The built-in compartment type particle inertial-capacitance damper is characterized in that one end of a ballscrew is inserted into a first metal shell through a nut, and the other end of the ball screw is inserted into a second metal shell through a bearing and welded to a flywheel; a plurality of compartments are arranged in the flywheel, the areas of the compartments are the same or different, a certain number of particles are placed in the compartments, the particle filling rates are the same or different, and thus the multi-frequency tuning function is achieved; and energy dissipation layers are attached to the inner walls of the compartments. When a controlled component vibrates to enable the first metal shell and the second metal shell to move relatively, the ball screw can drive the flywheel to rotate to generate inertial force, and vibration energy is absorbed; and the particles in the compartments of the flywheel move along with the flywheel and collide and rub with other particles and the energy dissipation layers to consume energy of the particles, and thus the purpose of energy dissipation is achieved. The built-in compartment type particle inertial-capacitance damper has the multiple functions of inertial-capacitance energy absorption, friction energy dissipation, multi-frequency tuning and the like, and vibration between structures under the effects of wind loads, earthquakes, blasting impact and the like can be effectively reduced.

Description

technical field [0001] The invention relates to a built-in compartment type particle inertial capacity damper, which belongs to the field of engineering vibration control. Background technique [0002] In recent years, with the development of social economy, the level of urbanization and the improvement of people's living standards, civil engineering structures are also developing towards higher heights, larger spans, and more complex structures. Encountering strong earthquakes, strong winds, and explosion shocks, there may be partial damage or overall damage, and the overall instability may also be caused by partial damage, which will bring serious loss of life and property to the society. At the same time, excessive deformation of the structure will cause discomfort to the users of the building structure, especially the excessive vibration acceleration. At present, in order to minimize the losses caused by accidental loads such as earthquakes and wind disasters, using dam...
