Embodiment
as Fig. 1, 2, shown in 3, upper, lower fixed frame 1, be provided with one or more permanent magnets 3 between 2, three have been provided in figure, permanent magnet 3 adopts ferromagnetic material, as neodymium iron boron, the top of permanent magnet 3 is connected on fixed mount 1 by upper reset spring 7, below by the next spring 8, being connected on lower fixed frame 2 of permanent magnet 3, how outside upper each permanent magnet 3 is can correspondence, lower back-moving spring 7, 8, lower back-moving spring 8 is sleeved on passive hydraulic cylinder 10, passive hydraulic cylinder 10 is fixed on lower fixed frame 2, permanent magnet 3 is fixed on the piston rod of passive hydraulic cylinder 10, be equipped with the coil 4 with magnetic core in the N.S of each permanent magnet 3 utmost point side, the arrangement of permanent magnet 3 is to be parallel to each other magnetic pole in the same way, be that each permanent magnet 3 all is arranged in order by the N.S utmost point or the S. N utmost point, between two permanent magnets 3, interval equates, be arranged in equably same plane, on same height, both sides at each permanent magnet 3, be that N.S utmost point both sides are equipped with a coil with magnetic core 54, coil and the mutual alternate intervals of permanent magnet 3 with magnetic core are arranged on sustained height, coil 4 upper ends and upper holder 1 with magnetic core are fixedly linked, lower end directly or by active hydraulic cylinder 9 indirectly and lower fixed frame 2 be fixedly linked, each coil 4 can corresponding a plurality of active hydraulic cylinders 9, initiatively the bottom cylinder barrel of hydraulic cylinder 9 and passive hydraulic cylinder 10 communicates by the oil sump 11 of oil pipe 12 and lower fixed frame 2 bottoms.Upper and lower fixed mount 1,2 adopts high-intensity nonferromagnetic material to make, as aluminum alloy materials; At the permanent magnet 3 of said structure and the outer peripheral magnetic core 6 of circle that is arranged with of the coil 4 with magnetic core, coil magnetic core 5 adopts high conductivity material making with peripheral magnetic core 6, as silicon steel;
Be arranged with at above-mentioned permanent magnet 3 with the coil 4 of magnetic core outer the peripheral magnetic core 6 complete magnetic loops that a trap is closed; In Fig. 1, the oil sump 11 of lower fixed frame 2 bottoms is connected with external active hydraulic cylinder 9 by oil pipe 12, when External Force Acting during at active hydraulic cylinder 9, initiatively the piston movement of hydraulic cylinder 9 forms fluid pressure, this pressure enters passive hydraulic cylinder 10 through oil pipe 12, oil sump 11 conduction, under hydraulic action, the piston driving permanent magnet 3 of passive hydraulic cylinder 10 moves up and down; In Fig. 2, initiatively hydraulic cylinder 9 is set in being, be fixed on lower fixed frame 2, its bottom cylinder barrel is connected with oil sump 11, initiatively the piston rod of hydraulic cylinder 9 is connected with upper holder 1 by the coil 4 with magnetic core, when upper holder 1 has external force or vibration, piston rod movement with moving winding 4 and active hydraulic cylinder 9, and then form fluid pressure in the cylinder barrel of active hydraulic cylinder 9, this pressure enters passive hydraulic cylinder 10 through the oil sump conduction, thereby the permanent magnet 3 that promotes to be fixed on passive hydraulic cylinder 10 pistons moves up and down; Initiatively hydraulic cylinder 9 all can, according to the practical application needs, be selected single-stage or multistage hydraulic cylinder with passive hydraulic cylinder 10; The long-pending sum of all active hydraulic cylinder 9 piston cross-sections is amassed the ratio of the ratio of sum referred to as sectional area with all passive hydraulic cylinder 10 piston cross-sections, in actual applications, for improving unit efficiency, for amplitude or produce the less energy source of displacement and should select the ratio of larger sectional area, simultaneously, passive hydraulic cylinder 10 adopts multistage; For amplitude or produce the larger energy source of displacement and should select the ratio of less sectional area, simultaneously, initiatively hydraulic cylinder 9 adopts multistage.
