The invention discloses a shafting transverse vibration large force value inertia type electromagnetic active control device. The device comprises a magnetic conductive shell, an upper end cover, a lower end cover, a wire frame, a spring radial fixing piece, a coil, magnetizers, a non-magnetic-conductive main rod, permanent magnets, a compression spring and a base, wherein the upper end cover and the lower end cover are fixed to the two ends of the magnetic conductive shell, and the wire frame, the spring radial fixing piece, the coil, the magnetizers, the non-magnetic-conductive main rod, the permanent magnets and the compression spring are arranged in the magnetic conductive shell. The base is fixed on the lower end cover. The main rod, the permanent magnets and the magnetizers form a rotor. The main rod is located on the central axis of the magnetic conductive shell, and two ends of the main rod are rotationally connected with the upper end cover and the lower end cover through bearings respectively. The permanent magnets and the magnetizers are alternately arranged on the outer side wall of the main rod in the axial direction of the main rod, the magnets located at the two ends are the magnetizers, the same poles of the adjacent permanent magnets are opposite, and the permanent magnets and the magnetizers located at the two ends of the permanent magnets form a closed magnetic circuit through the magnetic conductive shell. According to the device, the mover output force and the shafting vibration direction are opposite and the frequency is the same by adjusting the electrifying frequency and direction of the coil, so that the shafting transverse vibration is controlled.
本发明公开了一种轴系横向振动大力值惯性式电磁主动控制装置,该装置包含:导磁外壳,固定在导磁外壳两端的上端盖和下端盖,设置在导磁外壳内的线框架、弹簧径向固定件、线圈、导磁体、非导磁性的主杆、永磁体和压缩弹簧,以及固定在下端盖上的基座。其中,主杆、永磁体和导磁体构成动子。主杆处于导磁外壳的中轴线处,其两端分别通过轴承与上端盖和下端盖转动连接。永磁体和导磁体沿主杆的轴向交替排布在主杆的外侧壁上,且处于两端的磁体为导磁体,相邻的永磁体间同极相对,永磁体通过导磁外壳和处于永磁体两端的导磁体形成闭合磁路。本发明的装置通过调节线圈的通电频率和方向使动子输出力与轴系振动方向相反、频率相同,以控制轴系横向振动。
