摘　　要：针对磁流变液阻尼器价格昂贵及不易密封且易失效的问题,提出以多孔泡沫金属材料为载体,解决上述应用的瓶颈问题的新理念。介绍基于多孔泡沫金属材料的简易磁流变液阻尼器的概念设计,并对其可行性进行初步研究,初步研究结果表明多孔泡沫金属可以储存磁流变液,同时磁流变液在磁场作用下可以从泡沫金属溢出并实现阻尼功能。Aimed at the problems that MR damper is expensive, not easy to be sealed and easy to be disabled, a new method to applying the porous metallic foams as a carrier was proposed to solve these problems. The conception design of low-cost MR fluid damper based on porous metallic foams was introduced and feasibility was studied primarily. The initial results show that MR fluid can be stored in the porous metallic foams and drawn out to obtain the damping effect when the outer magnetic field is on.
