液压马达滑靴副倾侧状态下的静压支承特性分析

建立了描述滑靴副倾侧状态下的静压支承特性的数学模型，综合考虑了油液粘温效庆及流体动压效应对流场的影响，在此基础上通过数值方法求解流场控制方程，得到了滑块倾侧角度、曲轴转速以及温升对静压支承性能的影响关系，分析表明，滑靴倾侧对静压支承特性的影响随曲轴转速增大而增大，油液粘温关系对承载力影响较大，对抗倾能力影响不大。

Analysis on Hydrostatic Bearing Performance under Tilting Condition of Slipper Pair of Itydraulic Motor

By comprehensively considering the viscosity-temperature effect and hydraulic effect on the pressure distribution,a mathematical model was set up which can fully describe the characteristics of the hydrostatic bearing of the slipper pair in a crankshaft connecting rod motor under tilting condition. On the basis of numerically solving the control equations, the correlation between the tilting angle of the slipper, rotating speed of the crankshaft, temperature rise and bearing parameters was obtained. It is shown that the effects of slipper tilt on hydrostatic bearing increase with the rise of rotating speed of crankshaft. Viscosity-temperature effect has more influence on load carrying capacity, whereas, its effect on anti-tilt capability is rather small.
