Horizontal tuning frame type eddy current damper
The invention provides a horizontal tuning frame type eddy current damper. The horizontal tuning frame type eddy current damper comprises a supporting system, a spring mass system, an eddy current damping system and a negative stiffness system, wherein the supporting system comprises an outer frame and a guide rod; the spring mass system comprises a spring and a balancing weight; the eddy currentdamping system comprises a low-speed end permanent magnet, a high-speed end permanent magnet, a guide rail, a sliding block, a magnetism adjusting plate, a conductor plate and back iron; the negativestiffness system comprises a moving permanent magnet and a fixed permanent magnet; and the damper applies the magnetic field modulation principle and the concept of a negative stiffness nonlinear energy trap. The moving speed of the high-speed end permanent magnet is increased through the magnetism adjusting plate, and the energy consumption efficiency of the damper is improved. The movement of the balancing weight can be promoted through the tangential component of repulsive force between the permanent magnets of the same name, and therefore the vibration reduction frequency band is widened,robustness is better, and the problem that the vibration reduction effect is poor when a traditional tuning mass damper is out of order is solved.
本发明提供一种水平调谐的框架式电涡流阻尼器，包括支承系统、弹簧质量系统、电涡流阻尼系统和负刚度系统；所述支承系统包括外框架和导杆；所述弹簧质量系统包括弹簧和配重块；所述电涡流阻尼系统包括低速端永磁体、高速端永磁体、导轨、滑块、调磁板、导体板和背铁；所述负刚度系统包括运动永磁体和固定永磁体。本发明的阻尼器中应用了磁场调制原理和负刚度非线性能量阱的概念。通过调磁板加快高速端永磁体的运动速度，提高阻尼器的耗能效率；通过同名永磁体之间排斥力的切向分量可以促进配重块的运动，从而拓宽了减振频带，鲁棒性更好，弥补了传统调谐质量阻尼器失调时减振效果差的问题。
