【 中文摘要 】本发明公开了一种挤压式磁流变弹性体阻尼器，导磁外套筒内套设有螺线管，螺线管上缠有线圈绕组，线圈绕组与直流电源连接；螺线管内放有上、下磁流变弹性体，上、下磁流变弹性体之间设置有导磁活塞；上磁流变弹性体的上部设置有上导磁体；上磁流变弹性体和上导磁体上设有通孔，通孔内设有能够沿通孔上下移动的活塞杆，活塞杆的一端连接有上铰球座，活塞杆的另一端与导磁活塞固定连接；下磁流变弹性体的下部设置有下导磁体，下导磁体的下部连接有下铰球座。解决了现有技术中由于磁流变阻尼器的磁流变液密封难、易沉降而导致阻尼器性能下降的问题。本发明不需要对阻尼器进行绝对密封，磁性颗粒不会随时间而沉降，性能好。

【 英文摘要 】The invention discloses an extrusion type magnetorheological elastomer damper. A solenoid is sleeved in a magnetic conduction outer sleeve; a coil winding is wound on the solenoid and is connected with a direct-current power supply; an upper magnetorheological elastomer and a lower magnetorheological elastomer are arranged in the solenoid; a magnetic conduction piston is arranged between the uppermagnetorheological elastomer and the lower magnetorheological elastomer; an upper magnetic conductor is arranged at the upper part of the upper magnetorheological elastomer; through holes are formedin the upper magnetorheological elastomer and the upper magnetic conductor; a piston rod capable of moving up and down along the through holes are arranged in the through holes; one end of the pistonrod is connected with an upper hinge ball seat; the other end of the piston rod is fixedly connected with the magnetic conduction piston; a lower magnetic conductor is arranged at the lower part of the lower magnetorheological elastomer; the lower end of the lower magnetic conductor is connected with a lower hinge ball seat. Through the extrusion type magnetorheological elastomer damper, the problem that the performance of the damper is reduced because the magnetorheological fluid of the magnetorheological damper is difficultly sealed and is easily precipitated in the prior art can be solved; the damper does not need to be absolutely sealed; magnetic particles are not precipitated along with the time; the damper is excellent in performance.
