液靜壓軸承具有高運動精度、高剛性、高阻尼以及低摩擦阻力等優點,可以滿足次微米級高精度運動之需求,故在目前高精密、高負載的工具機產業應用甚廣。液靜壓系統之性能主要受工作流體的性質影響,例如潤滑油的黏滯係數、供油壓力等,本研究針對一液靜壓軸承系統,探討其在不同油液溫度與供油壓力下對性能的影響。
研究針對一液靜壓軸承,首先利用雷諾方程式與流量平衡式建立軸承模型,計算軸承承載力與剛性,並以模型為基礎分析液靜壓軸承性能在不同油液溫度與不同供油壓力下的軸承參數的變化,包含油腔壓力、承載力及剛性;隨後針對此液靜壓軸承改變油液溫度與供油壓力,同時對該軸承施加負載力,量測油液總流量、油腔壓力及軸承位移,再將量測數據與模型進行比較。結果顯示無論油液溫度或供油壓力,模型分析之結果皆高估其影響性,但誤差皆小於15%,顯示理論模型需進一步調整。
本研究之主要貢獻在於建構液靜壓軸承之油液溫度與供油壓力對該軸承性能影響之模型,並與實際量測結果進行驗證,理論模型與實際量測數據比較結果誤差小於15%,顯示本研究結果仍可提供液靜壓軸承設計之參考。


Hydrostatic bearings are widely employed in precision machine tools as it provides high stiffness, high damping and low friction. Performance of hydrostatic system is mainly affected by the working fluid properties such as viscosity coefficient of lubricants, supply pressure and the like. In this study, a hydrostatic bearing system is investigated in the effect of hydrostatic bearing at different temperatures and supply pressure on its properties.
This paper includes the experimental and numerical study of the mechanical behavior of hydrostatic bearing. Firstly, by using of the finite difference method and Reynolds equation the hydrostatic bearing static performance will be analyzed . In static analysis, the load capacity, stiffness and oil cavity pressure are determinded.
Second, The experiment have been done in variable-temperature, variable pressure and variable loading. measuring the total flow rate, oil cavity pressure, the displacement of the bearing. Finally, compare the bearing model with experimental results. The results showed that regardless of the oil temperature or oil supply pressure, analysis of the results of the model are overestimated its influence, but errors are less than 15%, indicating a theoretical model for further adjustments.
The main contribution of this study is to construct a oil pressure and temperature affect model for bearing performance. The experimental and simulation results are in a good agreement, and indicate the model still provide a reference to the design of the hydrostatic bearing.
