本文利用平面氣靜壓氣浮原理，針對不同規格的氣靜壓軸平面承實驗測試並予以模擬比較。首先根據文獻最佳化參數建立氣靜壓平面軸承之數學模型並利用有限差分法分析軸承間隙中之壓力分佈情形，然後建立一實驗平台來測試軸承之性能，而此實驗平台欲求之實驗特性為氣浮平台之承載力、流量及剛性，並針對測試數據與模擬結果進行比較並提出誤差原因，最後利用測試數據提出性能指數以及能源消耗量比較軸承之優缺。

The objectives of the thesis are comparing the simulation and testing result with different specification of the pneumatic plain bearing which is used non-contact characteristic of a pneumatic bearing in its application. Then, we analyze the model of the pneumatic plain bearing by the finite difference method, then the pressure distribution of the air film can be found out. And we set up the experimental platform to test the performance include the loading force、stiffness and flow rate . In the end, we show the comparison of these pneumatic plain bearings by the performance index and energy-saving.
