摘　　要：为了对某型桃形腔液力偶合器不同充液率下流场两相环流特性及转矩特性进行分析,建立了液力偶合器泵轮和涡轮的内流场模型,应用计算流体动力学软件CFX进行了液力偶合器部分充液工况内流场数值模拟研究。结果表明:通过流场数值模拟可以准确得到液力偶合器内流道的流动状态,可对液力偶合器的转矩传递性能进行预测,仿真结果为调速型液力偶合器的选型与设计提供一定的理论依据。In order to analyze the two-phase circulation characteristic and torque characteristic of a peach-shaped cavity hydrodynamic coupling under different filling rates. The flow field model for the pump wheel and turbine wheel was established. The numerical simulation of the flow field was carried out by using the computational fluid dynamics software CFX. The results show that the flow state of the hydrodynamic coupling can be accurately obtained by numerical simulation of the flow field, and the torque transmission performance of the coupling is predicted. The simulation results provide a certain theoretical basis for the selection and design of the variable speed hydrodynamic coupling.
