摘要
针对目前磁流变阀结构形式单一且体积大的不足,设计了一种结构紧凑的混合流动式磁流变阀,该磁流变阀阻尼间隙液流通道由轴向圆环流动和径向圆盘流动共同组成。介绍了混合流动式磁流变阀结构及工作原理;同时建立了其压降数学模型。在搭建的磁流变阀测试试验台上对其压降性能进行测试,具体分析了加载电流及模拟外加负载对所设计的磁流变阀进出口压差的影响。
Due to the disadvantages of the simple structure and big dimensions of the magnetorheological (MR) valve at present, a hybrid flow MR valve with compact structure was developed in this study. The fluid resistance gaps of this proposed MR valve was formed between the annular fluid flow path and the radial fluid flow path. The structure and working principle of the MR valve were expounded in detail. The mathematical model of pressure drop was derived too. Meanwhile, the experimental tests were carried out on the test rig. The relationships among the pressure drop, applied input current and simulating load cases were analyzed.
