摘　　要：从污染控制、润滑和密封三个方面研究了磁流变流体用作液压工作介质的可行性。配制了纳米铁粉磁流变流体,以此为介质,对设计的磁流变阀进行了实验研究。通过理论和实验研究表明该阀在小流量时可用作溢流阀;同时,该阀可以通过PWM方式实现对流量的控制。According to the study of pollution control, lubrication and pressurization, the feasibility of using magneto - rheological fluid as working medium for hydraulic system was been studied. The magneto - rheological fluid of iron nano - particles was used as working medium of hydraulic system, the designed magneto - rheological valve was studied. The result shows that this valve can be used as relief valve at little flow, and can be used to control the flow by PWM.
