摘要
为了对超精密空气静压主轴静态性能进行数值分析 ,利用有限元法求解空气静压轴承内的压力分布 ,计算径向和止推轴承的承载、刚度和供气流量。研究轴承参数对轴承静态性能的影响 ,提出空气静压轴承的设计准则。推导出精密主轴承载、径向刚度、轴向刚度和角刚度的计算公式。
To evaluate the static performance of the ultra precision Spindle,the finite element models were used to caluclate pressure distribution in the aerostatic bearing.The weight,stiffness and the supply air flow of aerostatic journal and thrust bearing were evaluated.Study the effect of bearing parameters on the static performance of the aerostatic bearing.The design rules for aerostatic bearing were proposed.The load,radial stiffness,axial stiffness and angular stiffness of precision spindle were formulated.The analysis method was tested to be right by the experiments.
