摘　　要：该文从Navier-Stokes方程着手,通过量纲分析略去微小量,再结合定流量供油的圆形油腔液体静压导轨系统油膜承载力模型,建立了液体静压导轨系统带有速度项的非线性油膜力模型,进而建立了液体静压导轨系统转台的动力学方程。同时,利用数值计算,并针对不同变量情况对液体静压导轨转台进行了动力学性能分析,研究结果对于深入研究液体静压转台系统的力学性能提供了理论依据。In this paper, the nonlinear oil-film force model with velocity terms of a hydrostatic slide turntable system is established, when taking no account of the minor terms of the Navier-Stokes Equations by dimensional analysis, and combining with the bearing capacity of an oil-film model for the steady-flow hydrostatic slide system with round oil chamber. Consequently, the dynamic equation of the hydrostatic slide turntable system is formulated. In addiction, the dynamic properties of the hydrostatic slide turntable system, subjected to different variables, are investigated by virtue of numerical simulation. Thus, the research results presented in this paper will provide a theoretical basis for the further investigation on dynamic properties of a hydrostatic oil-film turntable system.
