Inerter type tuning eddy current damper
The invention discloses an inerter type tuning eddy current damper. The inerter type tuning eddy current damper comprises an upper sealing cover, a lower sealing plate, a magnetizer, a second spiral spring, a ball screw inerter and a thrust bearing, an outer ring magnet mounting wall and an inner ring magnet mounting wall are arranged on the lower sealing plate, and the ball screw inerter comprises a screw and a flywheel in transmission connection with the screw; and the lower end of the ball screw inerter is arranged on the thrust bearing, the thrust bearing is mounted on the lower sealing plate, and the magnetizer is mounted on the flywheel and located between an outer ring magnet and an inner ring magnet. The ball screw inerter has a mass amplification effect, the mass amplification effect is adjustable, the disadvantage that a traditional tuned mass damper is small in mass and limited in vibration reduction effect is overcome, the performance of a conventional vibration isolator can be achieved, high-frequency excitation can be avoided, and high-frequency energy input can be reduced; and damping is provided through the eddy current technology, and the problem of liquid leakage of a conventional viscous damper can be solved.
本发明公开了一种惯容式调谐电涡流减振器，包括上封盖、下封板、导磁体、第二螺旋弹簧、滚珠丝杆惯容器、止推轴承，下封板上设置有外圈磁铁安装壁、内圈磁铁安装壁，滚珠丝杆惯容器包括丝杆、与丝杆传动连接的飞轮；滚珠丝杆惯容器的下端设置于止推轴承上，止推轴承安装于下封板上，导磁体安装于飞轮上并位于外圈磁铁和内圈磁铁之间。滚珠丝杆惯容器具有质量放大效应，且质量放大作用可调，克服了传统调谐质量阻尼器质量较小而减振效果的有限的劣势，既可以具备常规隔振器性能，又可以避开高频激励，减小高频能量输入；采用电涡流技术提供阻尼，可以避免常规粘滞阻尼器漏液的问题。
