| 摘 要： | 介绍了一种同时具有圆环形和圆盘形阻尼间隙的磁流变阀的原理、结构及其模型,建立了测试磁流变阀的磁流变液压执行器系统及基于dSPACE实时仿真系统的虚拟测试系统.研究结果不仅显示实际测试结果与理论模型的一致性,而且表明当电流增加到0.80A时同时具有圆环形和圆盘形阻尼间隙的磁流变阀能产生最大压降,并且在一定压力作用下对磁流变液具有最佳阻断能力.

| Abstract: | The principle,structure,and modeling of a magnetorheological(MR) valve simultaneously possessing annular and radial fluid flow paths are presented and the experimental testing setup based on dSAPCE real-time data acquisition interface is established in this paper.The results not only show that the tested results are consistent with the theoretical results but also indicate that the MR valve simultaneously possessing annular and radial fluid flow paths will induce the maximum pressure drop when the electrical coil is supplied a driving current larger than 0.80A and can block the MR fluid completely under a determinate inlet pressure. |
