在工具機的滑動件上，經常採用線性滑軌以降低滑動時的摩擦係數。而在精密工具機的滑動件上，則常採用液靜壓滑軌以更進一步降低摩擦以提升位置控制精度；並降低磨耗及提升系統阻尼及動態剛性。但液靜壓滑軌的構造較為複雜，參數眾多不易直觀的進行設計。而軸頸式液靜壓滑軌的設計相對簡潔；因而本研究將針對軸頸式液靜壓滑軌的設計進行相關研究。
本研究的目的為設計出符合業界需求的液靜壓線性滑軌。設計時主要藉由電腦模擬的方式來確認相關參數所產生的性能有達到要求，這些參數包含滑軌長度、軸承直徑、油膜厚度、供油壓力、油腔尺寸等等，對滑軌的性能影響包括變形量、傾斜角度、承載力、流量。並根據分析的結果找到最適當的參數組合，以做為軸頸式液靜壓線性滑軌的設計指標。
最後根據模擬結果選定適當參數設計軸頸式液靜壓線性滑軌、進行實驗與量測、探討模擬及實驗結果的差異。

Linear guide way is quite popular in machine tool design for its main advantage of low friction. For high precision machine tool, hydrostatic linear guide way is frequently adopted for its even lower friction and hence a higher precision control capability. Besides, the hydrostatic linear guide way provides the edge of low wear and higher damping/ dynamic stiffness. However, the design of hydrostatic linear guide way is relatively complex. The design of journal type hydrostatic guide way is relatively simple, therefore it is of interest to study the design of journal type hydrostatic guide way.
The purpose of this research is to reveal the procedures needed for the design of a journal type hydrostatic guide way to fulfill the need from industrial. The system parameters studied includes length and diameter of the shaft, film thickness, size of recess in the journal type guide way, supply pressure of bearing and et al. The performance of system studied includes deformation and tilting of the shaft, loading capacity, static stiffness and flow rate of the hydrostatic guide way are evaluated through simulations.
Based on the results, a test system is established to verify the simulation results. Series of experiments were conducted to verify the simulation results. Finally conclusions were made based on these results.
