Self-resetting self-balancing inerter based on rhombic transmission mechanism

Abstract

The invention relates to a self-resetting self-balancing inerter based on rhombic transmission. The self-resetting self-balancing inerter comprises a screw rod, two groups of energy consumption assemblies, transmission assemblies and a resetting assembly, the transmission assemblies are rhombic transmission assemblies and are connected with the energy consumption assemblies and the resetting assembly correspondingly, threads at the two ends of the screw rod are sleeved with the two groups of energy consumption assemblies correspondingly, and the energy consumption assemblies can rotate aroundthe screw rod in the opposite direction; and the resetting assembly comprises springs, the springs are connected with the transmission assemblies and the screw rod correspondingly, and the screw rod is provided with threads in the same direction. Compared with the prior art, the self-resetting self-balancing inerter has the advantages of being good in integrity, capable of achieving self-balancingand resetting, capable of avoiding resonance and the like.

Description

technical field [0001] The invention relates to the field of vibration control of civil engineering structures, in particular to a self-resetting and self-balancing inerter based on a diamond-shaped transmission mechanism. Background technique [0002] In the field of civil engineering structures, in addition to natural factors such as earthquakes, wind vibrations, and waves, the sources of vibration also include human factors such as transportation, machine operation, and construction blasting. Although the sources of various dynamic loads are different, the damage to civil engineering structures cannot be underestimated. Severe vibrations can cause houses to collapse, bridges to break, and casualties. Slight vibrations can also cause cracking and deformation of buildings, damage to non-structural components, etc., reducing the sense of safety and comfort of use. Regardless of the size of the vibration, the vibration of civil structures seriously threatens our life safety ...

Problems solved by technology

[0004] In recent years, the rapid earthquake rehabilitation strategy for structures has attracted the attention of the industry. It has become a better method to quickly improve the seismic performance of structures by using central energy-dissipating components combined with pure tension systems. Although the traditional rotary inerter with screw It already has a certain speed amplification capability, but it must rely on the relative motion of the stator and rotor to work. No matter how the rotor and stator are distributed, there must always be a braking torque to limit the rotation of the stator in order to make the inerter work. This makes it impossible Used in a pure tension system, the connection of the cable cannot provide such a braking torque
