本文主要研究的幾何模型為高壓軸油封(SEAL, OIL, ROATING, HP SHAFT)並將其延伸相關問題作為主要探討的方向，其零件主要功能為防止內部潤滑油漏出及外部灰塵或其他異物進入，零件位置位於引擎之高壓軸上，其前後分別連接了軸承與碳封。然而此幾何模型共有七個表面可作為數值分析的邊界條件，接著透過邊界元素法與ANSYS工程分析軟體來完成分析比對三維幾何模型的等向性金屬材料與異向性材料之熱傳問題、溫度及溫度梯度結果，然而透過這些表面使得分析更彈性且多變。
數值完成分析後，接著透過使用Microsoft Visual Studio軟體中視窗設計的功能:Windows Form application進行視窗介面設計，所設計的分析視窗能使操作者更直覺地輸入所需要的分析條件及參數並結合所設計的自動網格程式進行結果分析，藉由這個所設計的視窗一方面可以使操作上更簡易，另一方面也可以有效的減少分析時間。

This paper take the geometry which is high pressure shaft oil seal as the main discuss direction model, which is located on the high pressure shaft and the mating part in front of the oil seal is bearing and behind is carbon seal. There are two functions of the oil seal, first is prevent the internal lubricating oil leak out and the second is external dust or other stuffs enter. About this model, there are seven surfaces as the boundary conditions. Here we use two methods to finish analyze the temperature and gradient of three dimensional model’s isotropic and anisotropic materials, BEM(Boundary Element Method) as the tool of analyzing data and ANSYS which is computer-aided engineering software as the tool of Verifying data. Through these surfaces, they can make the analyze more flexible and varied.
After analyzing and comparing, use one of Microsoft Visual Studio software’s function, called windows form application, then use it to create a visual windows frame for analyzing the whole data. With this windows can let the operator more intuitive to key in the parameters which is needed and link the designed auto-mesh program to analyze. It’s not only can let operate more easily but can effectively reduce analysis time.
