Embodiment Construction
[0042] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0043] Such as figure 1 As shown, the present invention is a method for detecting the oil film lubrication performance of a static pressure turntable operating at a constant linear velocity. By theoretically analyzing the lubrication characteristics of a double rectangular cavity hydrostatic thrust bearing turntable operating at a constant linear velocity, the mechanism of the oil film flow in the gap is analyzed. Deduce the unsteady gap flow velocity equation and the instantaneous flow equation, including the following steps:
[0044] Step A: Analyze the operating characteristics of the static pressure turntable at constant linear velocity. The velocity field of the gap flow with acceleration boundary is composed of three parts: one is the flow caused by the pressure difference between the inlet and outlet, and the velocity field is distribute...
