摘　　要：齿轮泵是一种重要的液压元件,被广泛应用于实际工程中,为了验证CFD分析结果和试验结果的一致性,以某型号的外齿轮泵为例进行仿真分析与相关试验。结果表明:仿真结果与试验结果基本一致;通过研究出口流量的影响因素,验证了计算模型的正确性。这种方法不仅可以缩短产品开发周期,还为油泵的结构设计提供参考。Gear pump is an important hydraulic part and it＇ s used in many real projects. Combining finite analysis with test, a kind of external gear pump was taken as example, then the consistency of CFD analysis results and test results was verified. The results indicate the analysis results are consistent with the test results. The research for the outlet flux proves the analysis model is correct. This method can cut down design cycle and give vital data for the structure design of gear pump.
