Description
技术领域technical field
本发明涉及振动控制技术领域，具体涉及一种基于振动能量回收的电涡流调谐质量阻尼器。The invention relates to the technical field of vibration control, in particular to an eddy current tuned mass damper based on vibration energy recovery.
背景技术Background technique
在当今社会，各类阻尼器因为有对原建筑结构改动小、施工方便、减振控制效果显著等优点而被广泛关注，并在国内外的建筑结构中都有应用，如台北101大厦、上海中心等。传统的阻尼器采用液压黏滞阻尼器提供阻尼，在提供阻尼的同时，也会有一定刚度，无法做到刚度与阻尼的完全分离，影响设计分析。而且，液压黏滞阻尼器还存在漏油、不易养护、后期难以调节等问题，增加维护的难度和成本。In today's society, all kinds of dampers have been widely concerned because of their advantages such as small changes to the original building structure, convenient construction, and significant vibration reduction control effects, and have been used in building structures at home and abroad, such as Taipei 101 Building, Shanghai center etc. The traditional damper uses a hydraulic viscous damper to provide damping. While providing damping, it also has a certain stiffness. It is impossible to completely separate stiffness and damping, which affects design analysis. Moreover, the hydraulic viscous damper also has problems such as oil leakage, difficult maintenance, and difficult adjustment in the later stage, which increases the difficulty and cost of maintenance.
电涡流阻尼是对液压黏滞阻尼的一大创新。电涡流阻尼器的原理是，导体质量块在运动时切割磁感线，根据法拉第电磁感应原理，在导体内就会产生感应电动势，形成电涡流，将振动能量转化为导体的热量，从而实现振动控制。电涡流阻尼器的优势在于：磁体与导体之间没有直接接触，无摩擦阻尼和磨损；不受温度等环境影响；不存在漏油等状况，易于维护且耐久性好。Eddy current damping is a major innovation of hydraulic viscous damping. The principle of the eddy current damper is that the conductor mass cuts the magnetic induction line when it is moving. According to Faraday's electromagnetic induction principle, an induced electromotive force will be generated in the conductor to form an eddy current, and the vibration energy will be converted into the heat of the conductor, thereby realizing vibration. control. The advantages of the eddy current damper are: there is no direct contact between the magnet and the conductor, no frictional damping and wear; it is not affected by the environment such as temperature; there is no oil leakage, etc., it is easy to maintain and has good durability.
振动能量回收，就是回收这些通常直接被耗散掉的结构振动能量。一方面，土木工程结构可回收的能量较大，而且结构的是振动无处不在的；另一方面，土木工程结构振动能量的回收也存在诸多的挑战与困难，主要体现在土木工程结构具有小振幅、低频率的特点。Vibration energy recovery is to recover the structural vibration energy that is usually dissipated directly. On the one hand, the recoverable energy of civil engineering structures is large, and the vibration of structures is everywhere; on the other hand, there are many challenges and difficulties in the recovery of vibration energy of civil engineering structures, mainly reflected in the small Amplitude, low frequency characteristics.
发明内容Contents of the invention
本发明的目的就是为了克服上述现有技术存在的缺陷而提供一种能源利用率高、阻尼耐久性好的基于振动能量回收的电涡流调谐质量阻尼器。The object of the present invention is to provide an eddy current tuned mass damper based on vibration energy recovery with high energy utilization rate and good damping durability in order to overcome the above defects in the prior art.
本发明的目的可以通过以下技术方案来实现：一种基于振动能量回收的电涡流调谐质量阻尼器，该阻尼器包括底座、通过支座固定在底座中部的永磁体、套设在永磁体外侧并通过弹性单元与底座连接的质量块，所述质量块的中部设有凹槽，所述永磁体插设在所述凹槽中，所述凹槽两个相对设置的内壁上设有电流发生单元，所述电流发生单元与能量回收单元连接。The purpose of the present invention can be achieved through the following technical solutions: an eddy current tuned mass damper based on vibration energy recovery, the damper includes a base, a permanent magnet fixed in the middle of the base through a support, sleeved on the outside of the permanent magnet and The mass block connected to the base through the elastic unit, the middle part of the mass block is provided with a groove, the permanent magnet is inserted in the groove, and the two opposite inner walls of the groove are provided with a current generating unit , the current generating unit is connected to the energy recovery unit.
本发明的工作原理如下：底座保持固定，即永磁体保持固定，当质量块连接的建筑发生振动时，质量块会发生竖向振动，并带动电流发生单元发生竖向振动，电流发生单元切割永磁体的磁感线，在电流发生单元中产生电流，从而储存在能量回收单元中。本发明有两个阻尼减震过程，第一是通过弹性单元对质量块的振动起到阻尼，第二是通过永磁体与电流发生单元之间的切割磁感线，在电流发生单元中产生电涡流消耗振动能量，起到阻尼的效果。另外，产生的电涡流被储存，可用作照明，能量回收利用率高。The working principle of the present invention is as follows: the base is kept fixed, that is, the permanent magnet is kept fixed. When the building connected by the mass block vibrates, the mass block will vibrate vertically, which will drive the current generating unit to vibrate vertically, and the current generating unit will cut the permanent magnet. The magnetic field lines of the magnets generate current in the current generation unit, which is stored in the energy recovery unit. The present invention has two damping and shock absorption processes. The first is to damp the vibration of the mass block through the elastic unit, and the second is to generate electric current in the current generating unit through the cutting magnetic induction line between the permanent magnet and the current generating unit. The eddy current consumes vibration energy and acts as a damping effect. In addition, the generated eddy current is stored and can be used as lighting, and the energy recovery rate is high.
所述的质量块的底部设均匀有多个凹孔，所述弹性单元的一端插设在凹孔内，另一端与底座固定连接。The bottom of the mass block is uniformly provided with a plurality of concave holes, one end of the elastic unit is inserted in the concave holes, and the other end is fixedly connected with the base.
所述的弹性单元为刚性弹簧，所述刚性弹簧的直径与凹孔相匹配，所述弹性单元的数量为4～6个。由于刚性弹簧伸出凹孔到底座的距离很短，所以不会使质量块产生水平方向的移动。The elastic unit is a rigid spring, the diameter of the rigid spring matches the concave hole, and the number of the elastic unit is 4-6. Since the distance from the rigid spring protruding from the concave hole to the base is very short, the mass block will not move in the horizontal direction.
所述的电流发生单元包括固定在凹槽两个相对设置的内壁上的导磁板以及固定在导磁板上的导体板，所述导体板与能量回收装置连接，所述导体板与永磁体平行设置。在导体板的后方设置导磁板，可以增强磁场的强度，使得导体板切割磁感线产生的电涡流强度更大，振动能量消耗也更大。The current generating unit includes a magnetic conductive plate fixed on two opposite inner walls of the groove and a conductor plate fixed on the magnetic conductive plate, the conductive plate is connected with the energy recovery device, and the conductive plate is connected with the permanent magnet Parallel setting. The magnetically conductive plate is arranged behind the conductor plate, which can enhance the strength of the magnetic field, so that the eddy current generated by the conductor plate cutting the magnetic induction line is stronger, and the vibration energy consumption is also greater.
所述导体板的材料为铜或铝。The material of the conductor plate is copper or aluminum.
所述导磁板的材料中含有铁、镉或钴中的一种。The material of the magnetic conductive plate contains one of iron, cadmium or cobalt.
所述导体板与永磁体之间的距离为5～10mm，在此距离范围内，磁感应强度较强，导体板的发热耗能性能较好。The distance between the conductor plate and the permanent magnet is 5-10mm, within this distance range, the magnetic induction intensity is relatively strong, and the heat generation and energy consumption performance of the conductor plate is relatively good.
所述永磁铁的材料包括稀土永磁材料、钐钴、镍镉钴、铁氧体永磁材料中的一种。The material of the permanent magnet includes one of rare earth permanent magnet materials, samarium cobalt, nickel cadmium cobalt and ferrite permanent magnet materials.
所述能量回收单元包括蓄电池、发电机或充电电池中的一种。The energy recovery unit includes one of a storage battery, a generator or a rechargeable battery.
与现有技术相比，本发明的有益效果体现在：用电涡流阻尼代替传统的黏滞阻尼，能够改良传统的黏滞阻尼机制存在的缺陷，提高阻尼器的耐久性和减振性能，提高控制结构的安全性和耐久性。并结合振动能量回收技术，提高能源利用率，节能环保。Compared with the prior art, the beneficial effect of the present invention is reflected in that the traditional viscous damping is replaced by eddy current damping, which can improve the defects of the traditional viscous damping mechanism, improve the durability and vibration reduction performance of the damper, and improve the Control structure safety and durability. Combined with vibration energy recovery technology, energy utilization rate is improved, energy saving and environmental protection are achieved.
