摘　　要：流体静压轴承在精密、超精密领域有着广泛应用,其性能计算分析是应用该轴承的首要环节。针对传统计算方法效率低、过程复杂、容易出错等一系列问题,提出了一套基于COMSOL Multiphysics的流体静压轴承快速建模分析方法。该方法通过变量转化解决了边界条件设置的问题,实现了“薄膜流动”模块在流体静压轴承计算中的应用拓展。对比证明,该方法过程简单、效率高,为流体静压轴承求解问题提供了一种新的思路和解决方案。Hydrostatic bearing is widely used in the field of precision and ultra-precision.Traditional calculation method about static performance of hydrostatic bearing is inefficient.The calculation processes is complex and error-prone.A set of rapid modeling and analysis method for hydrostatic bearing based on COMSOL Multiphysics is proposed.This method solves the problem of setting boundary condition through variable transformation and realizes the application of“thin film flow”module of COMSOL Multiphysics in hydrostatic bearing calculation.The comparison shows that the method is simple and efficient,and provides a novel idea and solution for hydrostatic bearing.
