针对一种实际的四油腔闭式静压导轨设计方案
将导轨轮廓误差分解成具有不同波长的轮廓误差分量
应用油膜厚度均化分析方法
计算了不同轮廓误差分量对应的运动误差及静态均化系数.分析表明
轮廓误差分量的波长、油垫长度及运动直线度评定长度对静压导轨静态均化效应具有显著影响.因此
在设计时应优化油垫长度与运动直线度评定长度的比值
使静压导轨均化效应对于较宽波长范围的轮廓误差分量得以增强
从而减小运动误差与轮廓误差的比值
在提高导轨运动精度的同时降低其加工难度.
A new method is proposed to quantitatively analyze the motion errors of a typical closed hydrostatic guideway with four pads.The average film thickness is defined and the film reaction force variation is evaluated. A practical design is analyzed by the method
and the averaging coefficients with respect to profile error components with different wavelength are calculated. It is shown that the wavelength of profile error components
the length of the pad and the evaluation range of the motion straightness are the main influencing factors on the averaging effect of hydrostatic guideways. The ratio of pad length to motion straightness evaluation range ought to be optimized to make the averaging effect be more significant in a wider wavelength range of the profile error component
so as to improve the hydrostatic guideway precision and lower fabricating difficulty.
