摘　　要：以浙江帅锋精密机械制造有限公司研发生产的闭式双点肘节式高速超精密压力机为研究对象,研究静压轴承在压力机曲轴支撑端的应用。针对多油腔动静压轴承压力油流动的复杂性,使用计算流体动力学软件FLUENT对液体动静压轴承压力场分布进行研究。介绍了动静压轴承的理论知识和计算流体力学的数值理论,并对主轴转速和供油压力对动静压轴承承载特性的影响做了深入的分析。结果表明:随着供油压力或主轴转速的增加,承载能力随之线性增加。Based on the research background of the toggle type press with high speed and ultra-precision,hydrostatic bearing has been studied in the application of the press.Aimed at the complexity of hybrid oil flowing in the multi pockets of hybrid bearing,computational fluid dynamics software FLUENT is used to analyze the pressure field of liquid hybrid bearing.The influences of spindle speed and supply pressure on the carrying characteristics are comprehensively analyzed.The results show that with the increase of input pressure or spindle speed,the carrying capacity could be linearly increased.
