摘　　要：基于磁流体的性质随磁场强度变化及泡沫金属孔隙微小、均匀等特点,将磁流体与泡沫金属两种材料结合,提出了一种新型磁流体阻尼器.建立了新型磁流体阻尼器的阻尼力模型及其减振系统的非线性数学模型.通过实验验证了磁流体阻尼器的减振性能.结果表明,提出的非线性模型能较为准确地反映新型磁流体阻尼器的阻尼力特性和减振特性;在一定参数范围内,该磁流体阻尼器能满足振动系统对不同阻尼的要求.Based on the performance of Magnetic rheological （MR） fluid and the structural characteristics of foam metal, a new type of MR damper is proposed by combining the MR fluid and foam metal. The damping force model of the damper and the nonlinear mathematical model of vibration reduction system are established. Vibration reduction performance of MR fluid damper is validated through experimentation. The result indicates that the proposed nonlinear model could accurately express the damping force and vibration reduction performance of the MR fluid damper. Within some range of parameters, this kind of MR fluid damper can meet the different requirements for damping of vibration system.
