Description
技术领域technical field
本发明涉及一种半主动减振基座及控制方法，属于半主动减振基座。The invention relates to a semi-active vibration-damping base and a control method, belonging to a semi-active vibration-damping base.
背景技术Background technique
现有减振基座的阻尼材料以橡胶阻尼为主，在工程应用中老化现象，容易失效。同时橡胶阻尼属于被动阻尼，不可控制，因此目前的减振基座在实际应用中会受到限制。利用颗粒作为阻尼介质、颗粒的相互作用作为阻尼机理的颗粒阻尼系统可以克服粘弹性阻尼和材料结构阻尼的种种限制。颗粒阻尼器是在振动结构体上加工一定数量的孔洞，在其中填充适当数量的金属或非金属颗粒。大量的实验研究表明，当结构体发生振动时，颗粒之间及颗粒与孔壁之间发生摩擦和碰撞，从而进行能量耗散与转换，于是降低了结构的振幅。颗粒阻尼器具有减振频带宽、冲击力小、噪声小等优点。同时，这种阻尼器具有结构简单，耐高温，抗老化，特别适用于工作环境恶劣的场合。The damping material of the existing damping base is mainly rubber damping, which is prone to failure due to aging phenomenon in engineering applications. At the same time, rubber damping is passive damping and cannot be controlled, so the current damping base will be limited in practical applications. The particle damping system, which uses particles as the damping medium and the interaction of particles as the damping mechanism, can overcome the limitations of viscoelastic damping and material structure damping. The particle damper is to process a certain number of holes on the vibrating structure and fill them with an appropriate number of metal or non-metal particles. A large number of experimental studies have shown that when the structure vibrates, friction and collisions occur between particles and between particles and the pore wall, thereby dissipating and converting energy, thus reducing the vibration amplitude of the structure. The particle damper has the advantages of wide frequency band of vibration reduction, small impact force and low noise. At the same time, this damper has the advantages of simple structure, high temperature resistance and aging resistance, and is especially suitable for occasions where the working environment is harsh.
被动颗粒阻尼在实际应用过程中存在许多限制：1.在结构体处于低频段振动时，颗粒阻尼器内位于上半部的颗粒受到激励参与了能量的消耗，但是位于阻尼器下半部的颗粒由于自身重力的影响产生了不同程度的挤压，呈现了固态特性，导致下半部颗粒丧失了活性，几乎不参与减振，此时减振效果不明显；2.在结构体处于高频段振动时，整个阻尼器中的颗粒呈现液态属性，发生了颗粒的流动，此时颗粒之间、颗粒与器壁之间发生了剧烈的碰撞与摩擦，此时减振效果最为明显。但是由于结构体振动幅值较大，导致上半部颗粒的运动位移变大，颗粒之间的联系变得不够紧密，在一定时间内碰撞和摩擦的几率随着振动频率的增加反而减小，导致减振效果减弱，因此在高频段控制颗粒的行为尤为重要。There are many limitations in the practical application of passive particle damping: 1. When the structure is vibrating in the low frequency range, the particles located in the upper half of the particle damper are excited to participate in energy consumption, but the particles located in the lower half of the damper Due to the influence of its own gravity, different degrees of extrusion are produced, showing solid-state characteristics, resulting in the loss of activity of the lower half of the particles, and hardly participating in vibration reduction. At this time, the vibration reduction effect is not obvious; 2. When the structure is in high-frequency vibration At this time, the particles in the entire damper show liquid properties, and the flow of particles occurs. At this time, severe collisions and frictions occur between the particles and between the particles and the wall. At this time, the vibration reduction effect is the most obvious. However, due to the large vibration amplitude of the structure, the movement displacement of the particles in the upper part becomes larger, and the connection between the particles becomes not close enough. The probability of collision and friction within a certain period of time decreases with the increase of the vibration frequency. As a result, the vibration damping effect is weakened, so it is particularly important to control the behavior of particles in the high frequency band.

The larger the current, the larger the magnetic force, and the smaller the current, the smaller the magnetic force.
有益效果：本发明的半主动减振基座及控制方法，具有以下优点：Beneficial effects: the semi-active vibration damping base and control method of the present invention have the following advantages:
1.在结构体的振动频率处于低频段时，颗粒阻尼器内位于上半部的颗粒受到激励，参与了振动能量的消耗，呈现液态属性的颗粒被通电线圈中的磁场磁化，使得颗粒间的吸引力增强，增大摩擦，上半部颗粒上下运动的同时，借助磁滞力间接带动了下半部部分颗粒的运动，使得在低频段时，下半部的部分颗粒也参与了碰撞与摩擦；1. When the vibration frequency of the structure is in the low frequency range, the particles located in the upper half of the particle damper are excited and participate in the consumption of vibration energy. The particles showing liquid properties are magnetized by the magnetic field in the electrified coil, making the particles between particles The attraction is enhanced, and the friction is increased. While the particles in the upper half move up and down, the movement of the particles in the lower half is indirectly driven by the hysteresis force, so that in the low frequency band, some particles in the lower half also participate in the collision and friction. ;
2.在结构体处于高频段振动时，整个阻尼器中的颗粒呈现液态属性，由于结构体振动幅值较大，为了避免因为上半段颗粒的运动位移变大，导致颗粒之间的联系变得不够紧密这一现象，通过施加电磁场的方式可以约束过于松散的颗粒，使同层颗粒之间、不同层颗粒之间的接触碰撞的几率增大，进而增大颗粒阻尼的效果；2. When the structure is vibrating at a high frequency, the particles in the entire damper exhibit liquid properties. Due to the large vibration amplitude of the structure, in order to avoid the increase in the movement displacement of the particles in the upper half, resulting in a change in the connection between the particles Insufficient compactness, by applying an electromagnetic field, the particles that are too loose can be restrained, so that the probability of contact and collision between particles in the same layer and between particles in different layers is increased, thereby increasing the effect of particle damping;
3.由于颗粒的碰撞和摩擦中有部分能量以热的形式消耗掉，阻尼器外部附着吸热层既可以吸收阻尼器内部的热量，也可以吸收通电线圈发热。3. Since part of the energy in the collision and friction of the particles is consumed in the form of heat, the heat-absorbing layer attached to the outside of the damper can absorb both the heat inside the damper and the heat generated by the energized coil.
