The invention discloses a double-liquid controllable damper. The double-liquid controllable damper comprises an outer sleeve and an inner sleeve; the inner sleeve is arranged in the outer sleeve, wherein the side wall of the inner sleeve is connected with the outer sleeve through a plurality of springs, and the top and the bottom of the inner sleeve are attached to the top and the bottom of the outer sleeve; an excitation coil is wound around the inner wall of the outer sleeve, and a magnetorheological fluid fills the portion between the inner sleeve and the outer sleeve; a shear thickening fluid fills the interior of the inner sleeve, a ball seat is arranged at the bottom of the inner sleeve, a ball core is arranged in a groove of the ball seat and is connected with the ball seat througha wire, a through hole is formed in the bottom of the groove, an air pump is arranged in the ball seat, and an air pump air outlet communicates with the through hole; and a vibration sensor is arranged on the inner wall of the inner sleeve and is connected with an external controller through a wire, and when the vibration frequency is lower than a threshold value, a controller air pump is startedso that gas can be vented to the ball core, and the ball core constantly rotates and vibrates up and down. The double-liquid controllable damper integrates the advantages of both the magnetorheological fluid and the shear thickening fluid, and through synergistic action between both fluids, excellent mechanical properties can be achieved; and the structure is simple, assembling and disassembly areconvenient, and self-resetting can be realized.
