Description

一种多耗能方式相结合的空间阻尼器A Space Damper Combining Multiple Energy Dissipation Methods

技术领域technical field

本发明属于土木工程振动控制技术领域，涉及一种多耗能方式相结合的空间阻尼器。The invention belongs to the technical field of civil engineering vibration control, and relates to a space damper combined with multiple energy consumption modes.

背景技术Background technique

利用阻尼来吸能减震，最初应用于航天航空，军工，枪炮，汽车等行业中。从20世纪70年代后，国外开始逐步地把这些技术转用到建筑、桥梁、铁路等工程中，其发展十分迅速。到20世纪末，全世界已有近100多个结构工程运用了阻尼器来吸能减震。采用阻尼器减震是一种被动控制系统，是通过增加结构阻尼、耗散振动能量来减小结构响应。由于其装置简单、材料经济、减振效果好等特点，在实际结构控制中具有广泛的应用前景。阻尼器种类繁多，我国现行抗规将其分为位移相关型和速度相关型。位移相关型阻尼器的耗能与其自身变形和相对滑动位移有关，常用的有金属阻尼器和摩擦阻尼器。速度相关型阻尼器的阻尼特性与加载频率有关，常用的有粘滞阻尼器和粘弹性阻尼器。Using damping to absorb energy and shock absorption, it was originally used in aerospace, military, guns, automobiles and other industries. Since the 1970s, foreign countries have gradually transferred these technologies to buildings, bridges, railways and other projects, and their development has been very rapid. By the end of the 20th century, more than 100 structural projects around the world have used dampers to absorb energy and reduce shock. Shock reduction with dampers is a passive control system that reduces structural response by increasing structural damping and dissipating vibration energy. Because of its simple device, economical material, and good vibration damping effect, it has broad application prospects in actual structural control. There are many kinds of dampers, which are divided into displacement-related type and speed-related type in my country's current anti-regulation. The energy dissipation of the displacement-dependent damper is related to its own deformation and relative sliding displacement. Metal dampers and friction dampers are commonly used. The damping characteristics of speed-dependent dampers are related to the loading frequency, and viscous dampers and viscoelastic dampers are commonly used.

本发明是在已有的普通粘弹性阻尼器基础上，主要考虑传统阻尼器大多只在单轴方向上起作用，并且使用的耗能方式单一的问题，提出了一种多种耗能方式结合并且能在各个方向上都很好起到耗能减震的空间阻尼器，实现了提升阻尼器耗能能力的同时应用到空间各个方向上的目的。The present invention is based on the existing common viscoelastic damper, and mainly considers that most of the traditional dampers only work in a single axis direction, and uses a single energy consumption mode, and proposes a combination of multiple energy consumption modes. In addition, the space damper can well function as an energy-dissipating and shock-absorbing space damper in all directions, achieving the purpose of improving the energy-dissipating capacity of the damper and applying it to all directions in space at the same time.

发明内容Contents of the invention

本发明的目的是提供一种多种耗能方式相结合，在各个方向上都能起到良好控制作用的空间阻尼器，实现了提高单个阻尼器的耗能上限，改善原本阻尼器只能在单一方向上起主要作用的不足的功能。The object of the present invention is to provide a space damper that combines multiple energy consumption modes and can play a good control role in all directions, so as to realize the improvement of the upper limit of energy consumption of a single damper, and improve the original damper that can only be used in Insufficient features that play a major role in a single direction.

本发明的技术方案：Technical scheme of the present invention:

一种多耗能方式结合的空间阻尼器，包括外部壳体1、球形质量振子2、弹簧3、刚性杆4和粘性材料层5；A space damper combined with multiple energy dissipation methods, including an outer shell 1, a spherical mass vibrator 2, a spring 3, a rigid rod 4 and a viscous material layer 5;

两外部壳体1相对布置，其相对侧为球形空腔，球形空腔内表面涂覆有粘性材料层5；球形质量振子2位于两外部壳体1间形成的球形空腔内，通过其上的弹簧3实现连接；多个刚性杆4固定在球形质量振子2上，均与球面垂直，保证刚性杆4的顶端和粘性材料层5存在距离，该距离通过刚性杆4的长度调节。当所附属的主结构发生振动时，弹簧3带动球形质量振子2产生振动，刚性杆4顶端与粘性材料层5产生碰撞，粘性材料层5吸收振动能量。The two outer casings 1 are arranged opposite to each other, and the opposite sides are spherical cavities, and the inner surface of the spherical cavity is coated with a viscous material layer 5; the spherical mass vibrator 2 is located in the spherical cavity formed between the two outer casings 1, and passes through it. The spring 3 realizes the connection; a plurality of rigid rods 4 are fixed on the spherical mass vibrator 2, all of which are perpendicular to the spherical surface, ensuring that there is a distance between the top of the rigid rod 4 and the viscous material layer 5, and the distance is adjusted by the length of the rigid rod 4. When the attached main structure vibrates, the spring 3 drives the spherical mass vibrator 2 to vibrate, the top of the rigid rod 4 collides with the viscous material layer 5, and the viscous material layer 5 absorbs the vibration energy.

所述的球形质量振子2的质量根据安放处主结构的频率和荷载的振动频率来确定。The mass of the spherical mass vibrator 2 is determined according to the frequency of the main structure where it is placed and the vibration frequency of the load.

所述的弹簧3的刚度根据安放处主结构的频率和荷载的振动频率以及不同方向减振的要求来确定。The stiffness of the spring 3 is determined according to the frequency of the main structure where it is placed, the vibration frequency of the load and the requirements for vibration reduction in different directions.

所述的刚性杆4的长度根据安放处主结构不同方向减振的要求来确定。The length of the rigid rod 4 is determined according to the requirements for vibration reduction in different directions of the main structure where it is placed.

当阻尼器所附属的主结构发生振动时，通过弹簧3与外部壳体1连接的球形质量振子2也产生振动，与弹簧3形成了调谐质量阻尼器，抵消部分外部激励引起的主结构振动响应。同时球形质量振子2的振动会使刚性杆4顶端与粘性材料层5产生碰撞，通过碰撞消耗一部分振动能量，粘性材料层5吸收一部分振动能量。球形质量振子2通过在各个方向的弹簧3与外部壳体1的球形空腔内壁相连，在球形质量振子2各个方向上布置刚性杆4，所以球形质量振子2在空间各个方向上都能振动并与粘性材料层5产生碰撞。When the main structure attached to the damper vibrates, the spherical mass vibrator 2 connected to the outer shell 1 through the spring 3 also vibrates, forming a tuned mass damper with the spring 3, which offsets the vibration response of the main structure caused by part of the external excitation . At the same time, the vibration of the spherical mass vibrator 2 will cause the top of the rigid rod 4 to collide with the viscous material layer 5, a part of the vibration energy is consumed through the collision, and the viscous material layer 5 absorbs a part of the vibration energy. The spherical mass vibrator 2 is connected to the inner wall of the spherical cavity of the outer casing 1 through springs 3 in all directions, and rigid rods 4 are arranged in all directions of the spherical mass vibrator 2, so that the spherical mass vibrator 2 can vibrate in all directions in space and Collision with the viscous material layer 5 occurs.

本发明的有益效果：本发明的阻尼器对结构任意方向上的振动都能达到良好的耗能减振效果。通过调节各个方向弹簧的刚度、刚性杆的长度可以实现在不同方向产生不同减震效果的功能。Beneficial effects of the present invention: the damper of the present invention can achieve good energy dissipation and vibration reduction effects on vibrations in any direction of the structure. The function of producing different damping effects in different directions can be realized by adjusting the stiffness of the spring in each direction and the length of the rigid rod.
