磨损是流体动力元件性能降低和早期失效的主要原因,在各类磨损中,粘着磨损和磨料磨损的影响尤为明显。近年来,国外在研究液压元件寿命和可靠性的基础上十分重视流体动力系统的磨损研究。本文简要介绍流体动力系统中的磨损机理,影响磨损的因素。对美国流体动力研究中心近年来开展的磨损研究工作也作了介绍。 Abrasion is the main reason for the decrease of performance and early failure of fluid dynamic components. In various types of wear, the effects of adhesive wear and abrasive wear are particularly obvious. In recent years, overseas studies on the life and reliability of hydraulic components, attach great importance to the study of fluid dynamic wear. This article briefly introduces the wear mechanism in fluid power systems and the factors that affect wear. In the recent years, the research work on wear of the American Fluid Power Research Center was also introduced.
