摘　　要：摩擦副是液粘传动(Hydroviscous Drive,HVD)装置的核心部件,直接影响HVD装置的工作性能。摩擦副的主要变形形式为翘曲变形,是由于流体动压及摩擦力产生应力作用的结果,摩擦副变形后会对液粘传动性能产生直接影响。本文以径向油槽摩擦副为研究对象,基于ANSYS Workbench平台建立了摩擦副的流固耦合模型,分析了摩擦副动力传递性能,摩擦片变形及应力分布情况以及入口油压对其工作性能的影响。结果表明,有沟槽摩擦副能够显著提高油膜的承载能力。本文为摩擦副的设计和HVD装置工作性能分析提供了方法和依据。A friction pair, which is the crucial part of the hydro-viscous drive device, imposes an important effect on HVD （Hydroviscous Drive）. The deformation of friction pair is warpage deformation which is caused by dynamic pressure and friction during the process of engagement. The Fluid-solid coupling model of radial grooves friction pair is taken into account on the platform of ANSYS Workbench. The dynamic performance of the friction pair, deformation of the friction pair, strain and stress were analyzed,and the impact of inlet pressure is also taken into consideration . The predicted torque shows that a grooved disc is better than the non -grooved one. This method can be used to analyze the performance of HVD and to design friction pairs.
