Problems solved by technology

However, the traditional linear vibration absorber (such as TMD) has great limitations, because it usually only has a good vibration absorption effect near a specific frequency, and the traditional dynamic vibration absorber has a narrow frequency band, which can only be realized by the joint action of multiple vibration absorbers. multimodal control

Abstract

The invention relates to a multi threshold value control model of tuned mass damper, which belongs to the technical field of wind and earthquake resistance and vibration attenuation of civil engineering. The multi threshold value control model of tuned mass damper comprises a fixed baffle, connecting rods, a metal rubber rod, a spring, a viscous damper, a particle damping vessel, an inclined baffle, a sliding steel plate, a particle damping and a slide. The metal rubber rod is connected with the fixed baffle and the particle damping vessel through the connecting rods respectively. The spring is connected with the fixed baffle and the sliding steel plate through the connecting rods respectively. The viscous damper is connected with the fixed baffle and the particle damping vessel through the connecting rods respectively. A plurality of layers are arranged in the particle damping vessel , and each layer is provided with a particle damping with different particle sizes and the inclined baffles are arranged on both sides of each layer. The multi threshold value control of tuned mass damper has the advantages of high efficiency of vibration attenuation, short time and effect of absorbing vibration frequency bandwidth and can effectively suppresses the whole structural vibration of the structure.

Description

technical field [0001] The invention belongs to the technical field of wind resistance, earthquake resistance and vibration reduction in civil engineering, and in particular relates to a multi-threshold control type tuned mass damper. Background technique [0002] In recent years, destructive earthquake disasters have occurred frequently at home and abroad, which seriously threaten the buildings and structures that human beings depend on for their livelihood. How to improve the earthquake safety of civil engineering is of great significance. In traditional anti-seismic methods, the consumption of seismic energy is often consumed through the inelastic state of the main structure itself. Therefore, the application and promotion of new anti-seismic vibration reduction technology has become a very important development direction. [0003] After the towering structure is subjected to dynamic loads such as wind and earthquakes, it will cause a dynamic response of the structure, a...
