Taking axial hydrostatic bearing as an example, this paper presents output damp taking account of variation of oil viscosity and puts forward a new concept, influencing coefficient of ratio on output damps. The conclusion is that the ratio on output damps depends not only on the cubic order of oil clearance but also influencing coefficient of ratio on output damps. At the same time, the influencing coefficients under different work conditions are compared by computer simulation results. These results offer a theoretical foundation for flowing properties of fluid with variable viscosity.
