为了研究液黏传动油液承载力的变化，选取非惯性坐标系，从流体力学方程入手，推导得到液黏传动摩擦油液的雷诺方程，利用Rayleigh动压润滑原理求解径向油槽下油液压力分布，并对其进行仿真。仿真结果与实验结果对比表明：两者的变化趋势是一致的，但理论值比实验值偏高，考虑到摩擦片间形成的油膜并非每一处都是充足的，所以油膜压力的实际值总是小于理论值；摩擦片间有油槽区域的油液比无油槽区域的油液要更加充足，就油液的压力值而言，前者比后者更加符合理论值，但都符合仿真结果和实验值。仿真结果为油膜承载力的研究提供较好的指导。

In order to research the bearing capacity change of the oil within viscous friction drive,by choosing a non-inertial coor-dinate system,started from the hydrodynamic equations,the Reynolds equation of the oil within viscous friction drive were obtained. By using Rayleigh hydrodynamic lubrication theory,then pressure distribution of the oil under the radial groove was solved,and simu-lated. By comparing the simulation results with experimental results,it is found that both trends are consistent,but the theoretical data are somewhat higher than experimental data. In considering that the oil film within the viscous friction drive were not always sufficient everywhere,so the actual pressure value of oil film are always lower than the theoretical value. Within the viscous friction drive,the oil in the tank are more sufficient than that not in the tank,so to the oil pressure value,the former are more in line with theoretical value than the latter,but all of them are in line with the simulation results and experimental data. The simulation results can supply better guidance to the research of oil film bearing capacity.
