隨著精密工業技術的進步,液靜壓軸承已廣泛的應用於工具母機工業上,乃是憑藉著液靜壓本身所具之優點及設計技術的改良,以克服大型機具之工作台因摩擦而影響定位精度、使用壽命等問題。本研究將設計研發一主動式控制用於液靜壓軸承系統。此液靜壓軸承主要是應用有限差分法建構其數學模型,並透過分析液靜壓平面軸承的壓力分佈,了解軸承設計參數與能力值的關係,最後結合田口品質分析、基因遺傳演算法以及灰關聯分析作為最佳化設計方法,藉此獲得具高承載力、高剛性的單一液靜壓平面軸承。
完成軸承設計後,再搭配伺服閥並應用智慧型控制理論主動控制進入液靜壓軸承所需之流量及油槽壓力,使得油膜厚度保持不變,以維持工作台的平穩性,提高加工物件的精度。

With the progress of the precision industry, hydrostatic bearing has been used in mechanical tools widely, because of the hydrostatic has advantages and technical improvements by itself, it can be used to overcome the life of large-scale machinery and positioning accuracy due to friction. In this study, we would design an active control which was used to the hydrostatic bearing system. The mathematical model of hydrostatic bearing has built by the finite difference method, and then analyzed the pressured distribution of hydrostatic bearing, which could let understand the relationship between design parameters and ability value. The optimal method combined Taguchi Method with Genetic Algorithm and Grey Analysis, which could produce the high load capacity and high rigidity of the single hydrostatic plane bearing.
After completing of the bearing design, applying intelligent control theory to control servo valve, that could supply the required flow and pressure of hydrostatic bearing. In order to improve the accuracy of the processing object, we should control the film thickness remains unchanged and maintain a smooth table.
