磁流变液的摩擦学研究现状及展望

磁流变液的摩擦学性能对磁流变液的服役性能和耐久性能以及磁流变器件的设计和主动控制有着重要影响，在评价其性能时，应结合实际工况，将磁流变液的摩擦学性能作为一项重要指标进行考察。本文将磁流变液与电流变液和磁流体的摩擦学性能进行了对比，提出可以通过选择合适的摩擦改进剂来改善磁流变液边界润滑条件下的摩擦学性能。从两个角度综述了磁流变液的摩擦学研究现状，并指出发生在其中的边界润滑和颗粒自磨损问题严重影响磁流变液的服役性和耐久性。最后针对磁流变液摩擦学研究的不足，从设计摩擦磨损检测装置、建立流变与摩擦的联系和摩擦主动控制等角度对磁流变液的摩擦学研究在未来的进一步发展进行了展望。

Review and prospect of tribology study of magneto-rheological fluid

Tribological performance of magneto-rheological fluid is a key factor in the design and active control of magneto-rheological device，and also in the service performance and durability of magneto-rheological fluid.Based on the actual work condition，tribological performance should be an important indicator in the evaluation of performance. In this paper，comparison of the tribological performance of magneto-rheological fluid and electro-rheological fluid / magnetic fluid is made. The tribological performance can be improved by adding proper lubricant additives. The current tribological study of magneto-rheological fluid is reviewed. Future research directions including design of friction and wear testing apparatus，establishing relationship between rheology and friction，and active control of magneto-rheological device are proposed.
