隨著科技與經濟不斷發展，為了滿足人們不斷提高的生活需求，製造業水平也應相對提高。工具機產業與製造業存著密不可分的關係，工具機精益求精的發展，帶動製造業在生產效能及產品精度的表現，使工具機產業培養了最專業的人才與最密集的技術，工具機產業的發展帶動國家對外競爭力的影響不容忽視，也因此工具機產業被視為國家工業化程度的指標。未來的方向是開發設計大規格、高承載力、高剛性、高阻尼性的液靜壓導軌。因此為提升工具機產業邁向高精度的趨勢，導軌的最佳化設計成為一大重點。
本研究藉由本實驗室學長之前研究傳統液靜壓導軌油腔僅單一進油孔容易造成油腔內最高壓力集中於進油孔、傳統導軌設計主要依靠經驗來調整參數的情況。將重新運用有限差分數值計算方法、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，進行電腦模擬設計獲得最佳的導軌構形，尋求具壓力均勻分佈的液靜壓導軌，獲得具高承載力、高剛性、高阻尼性及高平穩性之液靜壓導軌，並通過實驗的方式來驗證其性能。

As technology and economic development, in order to meet the increasing needs , the manufacturing level should also be relatively increased. Machine tool industry keep a close relationship with the industry, the development of machine tools excellence, promote production efficiency and product performance of manufacturing precision in that machine tool industry has trained the most professional talent and the most intensive technology, machine tool industry promote the development of the country's external competitiveness effects can not be ignored, and therefore the machine tool industry is regarded as indicators of the level of national industrialization. Future direction is to develop the design of large-sized, high-capacity, high rigidity, high damping of hydrostatic rail. Therefore, to enhance the precision machine tool industry trend towards the optimal design of the rail to become a major focus.
This research study seniors in our laboratory before traditional hydrostatic rail system oil chamber into the hole is likely to cause only a single maximum pressure concentrated in the oil chamber into the hole, rely mainly on conventional rail design experience to adjust the parameters of the situation. The re-use of the finite difference numerical method, HTGA/Gray method of optimizing design and computer simulation designed to get the best rail configuration, seeking a uniform distribution of hydrostatic pressure rail obtained with high load capacity, high rigidity, high damping capacity and high stability of the hydrostatic rail system, and through experimental way to verify feasibility and practicality of this system.
