Based on computational fluid dynamics, friction lubrication theory and hydrostatic technology, the research on large size hydrostatic Guide-way that many heavy-duty vertical CNC lathes widely use, established simulation control equation of hydrostatic guide-way's interstitial fluid, adopted finite volume method, defined lubricating oil properties, set boundary conditions such as constant flow inlet, outlet pressure, wall and so on, made iterative computations, got hydrostatic thrust bearing's

The results of numerical calculation really reflect hydrostatic bearing's internal fluid flow state, and the simulation results provide theoretical basis for the design of practical engineering hydrostatic bearing.
