一种集成馈能功能的磁流变阻尼器A magneto-rheological damper with integrated energy-feeding function

技术领域 technical field

本实用新型涉及一种磁流变阻尼器，尤其涉及一种集成馈能功能的磁流变阻尼器。 The utility model relates to a magnetorheological damper, in particular to a magnetorheological damper with an integrated energy feeding function.

背景技术 Background technique

磁流变阻尼器是一种广泛应用于半主动控制系统中的新型智能阻尼器件。它主要是通过给阻尼器活塞绕线槽内的激励线圈施加一定大小的电流，产生磁场使得流经液流通道内的磁流变液的屈服强度发生变化，从而动态改变输出阻尼力。 The magnetorheological damper is a new type of intelligent damping device widely used in semi-active control systems. It mainly applies a certain amount of current to the excitation coil in the winding groove of the damper piston to generate a magnetic field to change the yield strength of the magnetorheological fluid flowing through the liquid flow channel, thereby dynamically changing the output damping force.

磁流变阻尼器所具有的毫秒级响应速度、大控制范围和大阻尼力输出的特点，使得它成为工业应用领域优秀的半主动执行器件。目前，磁流变阻尼器已在建筑物及桥梁的减振抗震系统、铁路机车车辆及汽车悬架系统的减振等方面取得广泛应用。但是，现有的磁流变阻尼器需要可调的磁场激励，这需要外部电源输入。而在一些特殊场合，比如偏远地区，电力很难送达；或由于自然灾害等原因导致供电难以持续保证，这些因素将限制磁流变阻尼器的应用领域。 The characteristics of millisecond-level response speed, large control range and large damping force output of the magneto-rheological damper make it an excellent semi-active actuator in the field of industrial applications. At present, magnetorheological dampers have been widely used in vibration reduction and anti-seismic systems of buildings and bridges, and vibration reduction of railway rolling stock and automobile suspension systems. However, existing MR dampers require adjustable magnetic field excitation, which requires an external power input. In some special occasions, such as remote areas, it is difficult to deliver electricity; or due to natural disasters and other reasons, it is difficult to ensure continuous power supply. These factors will limit the application fields of magneto-rheological dampers.

公开号为CN200710034309.2的中国发明专利“一种自供电磁流变智能减振系统”将结构振动的传感器与磁流变阻尼器的供电电源集成到小型永磁式直流电机上，通过布置在减振器外侧的齿条齿轮传动的方式来驱动直流发电机发电，达到给磁流变阻尼器供电的目的。但其局限性也比较明显，由于发电装置布置在阻尼器外侧，导致整个减振系统体积庞大，并且对工作环境要求较高。公开号为CN101550982A的中国发明专利“一种自供电磁流变阻尼器”提出一多叶片蝶形电磁式机械能量采集器，能量采集器安装在磁流变阻尼器的活塞底部。但该结构也有一定的局限性，由于磁流变液较稠，导致叶片转速比较慢，产生的电能不足以实现对阻尼器中的励磁线圈供电。 The Chinese invention patent with the publication number CN200710034309.2 "A self-supplied electromagnetic rheological intelligent damping system" integrates the sensor of structural vibration and the power supply of the magnetorheological damper into a small permanent magnet DC motor. The rack and pinion transmission on the outside of the vibrator drives the DC generator to generate power to achieve the purpose of supplying power to the magneto-rheological damper. However, its limitations are also obvious. Since the power generation device is arranged outside the damper, the entire vibration reduction system is bulky and has high requirements for the working environment. The Chinese invention patent "a self-supplied electromagnetic rheological damper" with the publication number CN101550982A proposes a multi-blade butterfly electromagnetic mechanical energy harvester, which is installed at the bottom of the piston of the magnetorheological damper. However, this structure also has certain limitations. Due to the relatively thick magnetorheological fluid, the rotation speed of the blade is relatively slow, and the generated electric energy is not enough to supply power to the excitation coil in the damper.

基于此，有必要提出一种新型集成馈能功能的磁流变阻尼器，实现阻尼器振动机械能的高效采集，并有效缩小阻尼器的外形尺寸。 Based on this, it is necessary to propose a new type of magneto-rheological damper with integrated energy-feeding function to realize the efficient collection of vibration mechanical energy of the damper and effectively reduce the overall size of the damper.

图5所示是本实用新型激励线圈及感应线圈中磁力线分布示意图。感应线圈9中产生的磁力线通过永磁铁17的N极进入隔片11及感应线圈绕线架13，到达活塞杆12内壁，再通过感应线圈绕线架13返回永磁铁17的S极，形成闭合磁路。 Fig. 5 is a schematic diagram showing the distribution of magnetic force lines in the exciting coil and the induction coil of the present invention. The magnetic lines of force generated in the induction coil 9 enter the spacer 11 and the induction coil bobbin 13 through the N pole of the permanent magnet 17, reach the inner wall of the piston rod 12, and then return to the S pole of the permanent magnet 17 through the induction coil bobbin 13 to form a closed magnetic circuit.

感应线圈9由两组独立线圈组成，分别缠绕于感应线圈绕线架13绕线槽内；两组独立线圈产生的感应电压可表示为： The induction coil 9 is composed of two groups of independent coils, which are respectively wound in the winding slots of the induction coil winding frame 13; the induced voltage generated by the two groups of independent coils can be expressed as:

(1) (1)

(2) (2)

公式(1)和(2)中E _m为最大感应电动势，ω为激振频率。 In formulas (1) and (2), E _m is the maximum induced electromotive force, and ω is the excitation frequency.

由于感应线圈9在往复运动中产生交流电，可通过整流电路将交流电转换为两相直流电。 Since the induction coil 9 generates alternating current during the reciprocating motion, the alternating current can be converted into two-phase direct current through the rectification circuit.

激励线圈7中产生的磁力线通过活塞8，经过液流通道中的磁流变液，到达外套筒4，再经过液流通道返回活塞8，形成闭合磁路。 The magnetic field lines generated in the excitation coil 7 pass through the piston 8, pass through the magnetorheological fluid in the liquid flow channel, reach the outer sleeve 4, and then return to the piston 8 through the liquid flow channel to form a closed magnetic circuit.

本实用新型工作原理如下： The working principle of the utility model is as follows:

当存在外部激励时，活塞杆12沿轴向方向作相对运动，带动感应线圈绕线架13作往复运动，在永磁铁17作用下，缠绕在感应线圈绕线架13中的感应线圈9在往复运动中将产生交流电，通过整流电路将产生的交流电转换成两相直流电，从而可直接用于活塞8绕线槽内的激励线圈7的直流供电，通过给激励线圈7供电，产生磁场，改变活塞8与外套筒4之间形成的阻尼间隙内的磁流变液屈服强度，产生可控阻尼力，从而完成振动机械能量回收。 When there is an external excitation, the piston rod 12 moves relative to the axial direction, driving the induction coil bobbin 13 to reciprocate, and under the action of the permanent magnet 17, the induction coil 9 wound in the induction coil bobbin 13 reciprocates AC power will be generated during the movement, and the generated AC power will be converted into two-phase DC power through the rectifier circuit, so that it can be directly used for DC power supply of the excitation coil 7 in the winding groove of the piston 8. By supplying power to the excitation coil 7, a magnetic field is generated to change the piston. The yield strength of the magnetorheological fluid in the damping gap formed between 8 and the outer sleeve 4 generates a controllable damping force, thereby completing the recovery of vibration mechanical energy.

如果激励线圈7由外部电源单独供电时，馈能工作中采集转换过来的直流电也可储存在储能电路中。 If the excitation coil 7 is powered by an external power source alone, the DC power collected and converted during the energy feeding operation can also be stored in the energy storage circuit.
