The invention discloses a magnetorheological elastomer vibration absorber for a gearbox base, and relates to a vibration damper. The passive vibration absorber aims at solving the problem that an existing passive vibration absorber can only carry out vibration reduction and isolation on a single frequency. The passive vibration absorber comprises a shell, an oscillator iron core, a coil and a shear type magnetorheological elastomer. The shell and the vibrator iron core are both made of a magnetic conductive material; the shell is a cylindrical shell of which one end is provided with a hole; one end of the vibrator iron core is inserted into the shell, and a gap is formed between the outer side wall of the other end of the vibrator iron core and the inner side wall of the hole; the coil is positioned in the shell and sleeves the outer circumference of the vibrator iron core; the shape of the shear-type magnetorheological elastomer is a ring matched with the gap, and the inner ring wall and the outer ring wall of the shear-type magnetorheological elastomer are respectively fixed with the outer side wall of the other end of the vibrator iron core and the inner side wall of the hole.
齿轮箱基座磁流变弹性体吸振器,涉及一种减振装置。目的是为了克服现有的被动吸振器只能够针对单一的频率进行减隔振的问题,包括壳体、振子铁芯、线圈和剪切型磁流变弹性体;壳体与振子铁芯均由导磁材料制成;壳体为一端开孔的圆柱形壳体;振子铁芯一端插入壳体内,且振子铁芯另一端的外侧壁和孔的内侧壁之间具有间隙;线圈位于壳体内,且套设于振子铁芯的外圆周;剪切型磁流变弹性体的形状为与间隙匹配的环形,该剪切型磁流变弹性体的内环壁与外环壁分别与振子铁芯另一端的外侧壁和孔的内侧壁固定。
