Abstract

The invention relates to a multi-dimensional electromagnetic intelligent vibration reduction device, in particular to a protective device for high-rise structures such as power transmission towers. Inparticular, the outer part of an upper part is provided with a rod piece which is fixedly connected to a structure, when the vibration occurs in the horizontal direction, a ball screw drives upper discs to rotate, and after a spring is stretched, a magnetically controlled shape memory alloy is stretched, so that the magnetically controlled shape memory alloy deforms and consumes energy; a middlepart is provided with a middle disc which can rotate universal freely, a mass ball which is filled with damping liquid and can roll freely is placed on the middle disc, when the mass ball shakes, themass ball impacts piezoelectric ceramics which are installed all around the middle disk, the generated current is collected to an upper current collector, when the current reaches a certain value, theelectrical circuit is disconnected, and a magnetic field disappears suddenly, so that the magnetically controlled shape memory alloy shrinks to the original shape trend, the energy consumption of theupper part is increased; the upper part and the middle part are not firmly connected, so that the energy consumption occurs when torsion of the structure occurs; and when the structure vibrates in the vertical direction, the lower part and the middle part are connected with springs so that the the upper and middle parts of the device can vibrate to consume energy. The multi-dimensional electromagnetic intelligent vibration reduction device is easy to install and disassemble, has strong energy consumption capacity, and has a wide range of anti vibration functions.
