Abstract

The invention provides a micro-wind vibration energy consumption suppression device for a service steel pipe tower rod part, and the device is suitable for vortex-induced wind vibration control of animportant lattice type steel pipe tower framework part such as a power transmission tower. The micro-wind vibration energy consumption suppression device is composed of a steel sleeve sheet, a first viscoelastic material, a second viscoelastic material, SMA springs, a flow guide sheet, connecting bolts and connecting plates. The device has a two-stage micro-wind vibration control effect, can destroy the Karman vortex to inhibit or reduce the generation of micro-wind vibration, and can completely achieve the purpose of controlling the micro-wind vibration of a steel pipe component through the deformation consumption of the viscoelastic materials. Meanwhile, the SMA springs with the super-elastic effect are connected between the steel pipe and the steel sleeve, so that the device has a remarkable self-resetting capability. The device is simple in structure, light in structure, flexible in arrangement, low in manufacturing cost and convenient to replace. The device has the self-resettingcapability, is strong in resistance to external interference and is good in robustness; and the two-stage micro-wind vibration control principle is achieved, the vibration control effect is remarkable, good social and economic benefits are achieved, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to a breeze vibration control device for steel pipe tower components, which is mainly used for vortex-induced wind vibration control of important lattice steel pipe tower components such as transmission towers and communication towers. Background technique [0002] With the rapid development of my country's national economy, there is an urgent need for large-capacity, long-distance, low-loss UHV transmission lines to balance the unequal supply and demand of power resources. In recent years, a number of 1000kV UHV transmission lines have been established in my country. Due to their large spans and high tower heights, traditional angle steel towers can no longer meet the needs of structural strength, so steel pipe towers are generally used. The aerodynamic performance of the round section steel pipe member is good, and the wind pressure shape coefficient is only a...
