Abstract: 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.
