A self-resetting and self-balancing inerter based on a diamond-shaped transmission mechanism

Abstract

The invention relates to a self-resetting and self-balancing inerter based on diamond transmission, which includes a screw rod, an energy dissipation component, a transmission component and a reset component, and the transmission component is a rhombus transmission component, which is connected to the energy consumption component and the reset component respectively , the energy dissipation components are set in two groups, which are respectively sleeved on the threads at both ends of the screw rod, and can rotate around the screw rod in opposite directions. The reset component includes a spring, and the spring is connected to the transmission component and the screw rod To connect, the screw rod is provided with threads in the same direction. Compared with the prior art, the present invention has the advantages of good integrity, self-balancing and reset, and avoiding resonance.

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
