一种电磁流体阻尼器

Electromagnetic fluid damper

Abstract

The invention relates to an electromagnetic fluid damper. The electromagnetic fluid damper comprises an upper part and a lower part which are independent of each other, wherein the upper part comprises an upper disc flange (1), an electromagnet block (9) and a first pressing block (4); the electromagnet block is fixed in the upper disc flange through the first pressing block (4); the lower part of the electromagnetic fluid damper comprises a disc (10), a lower disc flange (19) which is arranged opposite to the disc, and a hydraulic cylinder (11) for no-leakage connection of the disc and the lower disc flange; the lower disc flange, the disc and the hydraulic cylinder form a closed no-leakage space, and the closed no-leakage space is full of damping fluid (12); the lower part of the electromagnetic fluid damper also comprises a piston (14), a round shaft (7), a first spring (8), a second spring (20), a permanent magnet block (17) and a second pressing block (13); a round hole (21) is formed in the circle center of the piston (14); a magnetic force and the springs are used for driving the piston in the damper to move; and when the piston moves, the damping liquid flows through a small round through hole on the piston, and consumes energy when flowing through the small round through hole on the piston.
本发明涉及一种电磁流体阻尼器,包括相互独立的上下两部分,上部分包括:上部圆盘法兰(1)、电磁铁块(9)、第一压块(4);电磁铁块通过第一压块(4)固定在上部圆盘法兰内;该阻尼器下部分包括:圆盘(10)、与圆盘相对设置的下部圆盘法兰(19)、将圆盘与下部圆盘法兰无泄漏连接的液压缸(11),下部圆盘法兰、圆盘和液压缸组成封闭式无泄漏空间,阻尼液(12)充满该封闭式无泄漏空间;所述阻尼器下部分还包括活塞(14)、圆轴(7)、第一弹簧(8)、第二弹簧(20)、永磁铁块(17)、第二压块(13),在活塞(14)的圆心处设有圆孔(21),利用磁力和弹簧推动阻尼器中的活塞运动,当活塞运动时,阻尼液流过活塞上的小圆通孔,阻尼液流过活塞上的小圆通孔时耗能。
