Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. This embodiment is a simulation test for the vibration suppression of a certain engineering structure. The natural frequency of the vibration reduction of the structure is w=15, and the optimal damping ratio is 4%-6%. According to the vibration reduction requirements of the engineering structure, the mass block is determined. The size of the iron block 7 is 100mm×100mm×100mm, the material is Q235 steel, and the weight is 16kg; the material of the end plate 8 is Q235 steel, the size is 150mm×150mm×10mm; there are four springs 10 between the end plate 8 and the iron block 7 The stiffness coefficient k=3619N / m; the size of the aluminum plate 3 is 150mm×400mm×20mm; the size of the rubber pad 5 is 10mm×100mm×100mm; the strength of the strong magnet 4 is 5000 gauss, and the size is 10mm×60mm×60mm; The two ends of the coil 2 generate a voltage of 5V, which can d...
