摘　　要：采用边界元法,对各种偏心率下错位浮环轴承和螺线浮环轴承的流体动力特性、流场和摩擦损耗进行了分析,并对各种偏心率下错位浮环轴承和螺线浮环轴承的摩擦损耗进行了定量研究,结果表明:在相同偏心率下,错位浮环轴承比螺线浮环轴承承载能力高、摩擦损耗低。The hydrodynamic characteristics of lubricant and flow field in different eccentrics in dislocated floating-ring bearing and spiral floating-ring bearing is studied by means of boundary element method.Furthermore,the quantitative analysis of friction power consumption in the both bearings is studied.The conclusion is that dislocated floating-ring bearing is higher in capacity and lower in friction power consumption compared with spiral floating-ring bearing.
