摘要	本文基于ANSYS WORKBENCH、FLUENT仿真软件，对液压滑阀因热力耦合形变和油液污染而卡滞的问题进行了数值仿真研究，研究结果为高可靠性液压阀的设计提供了参考依据和指导。
其他摘要	The reliability of hydraulic valve has a directly influence on the reliability of hydraulic system.Hydraulic spool valve is a kind of the common configurations.Due to the small gap of the spool and body,there are reliability problems such as sticking during the process of using.In this papper,the problem of hydraulic valve sticking for fluid-solid-heat coupling deformation and contamination were explored deeply by theoretical analysis and numerical simulation.The investigative results showed that there exists asymmetrical temperature distribution of fluid and solid in the spool valve leading to abovious partial deformation of spool and body.The distribution of particles was nonuniform even gathered partially.The shape of orifice,opening,density,diameter and viscosity have a influence on flow and distribution of solid particles.
