摘　　要：采用计算流体动力学(CFD)方法,对循环圆直径为468mm的开式液力减速器进行了温度场计算。经过仿真计算和分析,得到在全充液工况下液力减速器温度与转子转速的关系曲线,并对其内部温度场进行了分析。在此基础上,对开式液力减速器在相同转速、不同充液率的工况下进行了数值计算,得到温度与充液率关系曲线。通过仿真分析,为开式液力减速器在各个档位制动时的热交换问题提供了重要的理论依据。Computational Fluid Dynamics （CFD） method is employed to compute the temperature field of open-type hydrodynamic retarder with an effective diameter of 468 mm. By simulation and analysis, the relationship between temperature and rotating speed of the hydrodynamic retarder in the condition of full filled liquid is obtained. The internal temperature field of the hydrodynamic retarder is analyzed. On that basis, the open-type hydrodynamic retarder under the conditions of the same rotating speed and different liquid filling rates are computed. The relationship between temperature and liquid filling rate is obtained. Through simulating, it provides an important theoretical basis for the heat exchange of open-type hydrodynamic retarder at different gears.
