摘　　要：论文对液压系统中先导阀的使用进行了介绍,简单介绍了研究的背景,应用Ansys的Fluent软件对先导阀的液压油流动特性进行了CFX分析,对液压油中颗粒污染物在先导阀阀芯的运动特性,如运动速度矢量和运动轨迹等进行了计算。论文为液压系统的污染控制和故障诊断技术的研究提供了重要依据。The thesis introduced the use of the pilot valve in the hydraulic system and the background of the study, analized the hydraulic oil flow characteristics of pilot valve by using CFX of the software applications Ansys Fluent, calculated the features of movement in the pilot valvethe core of the particulate pollutants in the hydraulic oil, such as the movement velocity and vector trajectory. It provides an important basis for the hydraulic system of pollution control and fault diagnosis technology.
