Numerical Analysis of Bias Load on Integral Flotation Cushion

Abstract:

This paper adopts the Reynolds equation as the governing equation of gas lubrication; it mainly focuses on the complex flow field of flotation cushion with multiple supply-holes and analyzes the gas pressure distribution of bias load on the integral flotation cushion by the numerical method. At the same time, according to the mass conservation principle, an efficient revision iteration route about outlet pressure boundary condition of each supply-hole has been set, and the pressure distribution and flow rate of each supply-hole at different declination are calculated. The results show that when the flotation cushion deflection angle varies, due to the edge deflation, the outlet pressure of the orifice is not in strict inverse proportion to the thickness of gas film on the orifice on the integral flotation cushion.
