Description

柔性全向调谐质量阻尼器Flexible omnidirectional tuned mass damper

技术领域technical field

本实用新型属于工程结构振动控制技术领域,具体涉及一种柔性全向调谐质量阻尼器。The utility model belongs to the technical field of engineering structure vibration control, in particular to a flexible omnidirectional tuning mass damper.

背景技术Background technique

随着社会的发展,高层建筑和大跨度的桥梁越来越多,此类建筑的特点是强度和刚度满足需求,但其自身的振动频率通常比较低,如果通过提高自身固有频率和改变结构,往往成本会大幅度增加。此外,一些高层建筑、塔型建筑等在风载荷作用下会发生共振产生大幅度的摆动。在工程设计中,通过增加调谐质量阻尼器实现减振抑振是一种常见的方式。调谐质量阻尼器(TUNED MASS DAMPER,简称TMD),它是附加在主结构,其固有频率接近主结构的固有频率。当主结构振动时,TMD会产生一个相反的惯性力,使主结构的振动得到衰减。TMD系统能有效降低主结构的振动反应,对结构的振动有明显的控制效果,在高层和高耸结构抗震、抗风控制中有广阔的应用前景。With the development of society, there are more and more high-rise buildings and long-span bridges. This type of building is characterized by strength and stiffness to meet the needs, but its own vibration frequency is usually relatively low. If by increasing its own natural frequency and changing the structure, Often the cost will increase substantially. In addition, some high-rise buildings and tower buildings will resonate and swing greatly under the action of wind load. In engineering design, it is a common way to achieve vibration reduction by adding a tuned mass damper. The tuned mass damper (TUNED MASS DAMPER, referred to as TMD), which is attached to the main structure, has a natural frequency close to the natural frequency of the main structure. When the main structure vibrates, TMD will generate an opposite inertial force, which will attenuate the vibration of the main structure. The TMD system can effectively reduce the vibration response of the main structure, and has an obvious control effect on the vibration of the structure. It has broad application prospects in the anti-seismic and wind-resistant control of high-rise and towering structures.

目前的现有调谐质量阻尼器在应用中位置不能很好的进行固定,且在使用后需外力进行复位后才能再次精准使用,若不复位可能出现偏差,不便于重复工作。现有调谐质量阻尼器大都都是在一个方向或者两个方向上减振效果明显,但对全向调节灵敏度低,减振效果不理想。现有调谐质量阻尼器不能很好地兼顾横向和竖向减振。现有调谐质量阻尼器对装置内部的组件防氧化保护措施不够,影响装置的使用年限。The current existing tuned mass damper cannot be fixed well in the application, and it needs to be reset by external force after use before it can be used accurately again. If it is not reset, deviation may occur, which is not convenient for repeated work. Most of the existing tuned mass dampers have obvious vibration reduction effect in one direction or two directions, but the sensitivity to omnidirectional adjustment is low, and the vibration reduction effect is not ideal. Existing tuned mass dampers cannot balance lateral and vertical vibration reduction well. The existing tuned mass damper does not have enough anti-oxidation protection measures for the components inside the device, which affects the service life of the device.

本装置在使用之前先将柔性阻尼组件3安装至外壳1的内部,然后加入阻尼液,使得外壳1内部的组件均处于阻尼液的内部,然后将端盖2与外壳1密封,这样能够使得内部形成密封状态,这样各个组件浸泡在阻尼液中且形成密封可以最大程度防止内部元件氧化,同时油液也具有一定的粘滞阻尼,也能起到减振的作用。Before using the device, the flexible damping component 3 is installed inside the housing 1, and then damping fluid is added, so that the components inside the housing 1 are all inside the damping fluid, and then the end cover 2 and the housing 1 are sealed, so that the internal A sealed state is formed, so that each component is soaked in the damping fluid and forms a seal to prevent the oxidation of internal components to the greatest extent.

工作状态:当该装置受到主结构振动带来横向运动时,活动块7在万向轮14的作用下进行运动,带动配重盘和质量块一起运动,三个组件运动会对阻尼液产生扰动,而阻尼液会反作用三者上,同时阻尼弹簧9在三者的运动下进行有阻尼的伸缩运动,会消耗三者的运动,从而对主结构的横向起到减振的作用。当该装置受到来自竖向运动时,质量块会产生运动,质量块运动带动支撑弹簧5运动,支撑弹簧5自身有消耗能量的作用,因此可抵消质量块的竖向运动,从而对主结构的竖向起到减振作用。Working state: when the device is subjected to lateral movement caused by the vibration of the main structure, the movable block 7 moves under the action of the universal wheel 14, driving the counterweight plate and the mass block to move together, and the movement of the three components will disturb the damping fluid. The damping fluid will react on the three, and the damping spring 9 will perform a damped telescopic movement under the motion of the three, which will consume the motion of the three, thereby reducing the vibration of the main structure in the transverse direction. When the device is subjected to vertical motion, the mass block will move, and the movement of the mass block will drive the support spring 5 to move, and the support spring 5 itself has the effect of consuming energy, so it can offset the vertical movement of the mass block, thereby affecting the main structure. Vertically acts as a shock absorber.
