本研究提出一個設計方法，以田口實驗計劃法與電腦輔助工程分析（CAE）來最小化耐壓型油封與軸之間的密封寬度，經由模擬相關設計參數與各種不同操作環境，研究不同參數對密封寬度之影響，進而達到最佳化設計，同時取代實際的實驗量測以節省開發時程及成本。研究中以一個直徑38mm的唇型油封為設計案例，依據唇部接觸壓力對橡膠材料Mooney-Rivlin性質與油封幾何尺寸在不同密封環境下之響應，將此油封設計最佳化。結果顯示本設計方法提供旋轉型唇型油封一有效的設計工具。

In this research, a design methodology for minimizing the contact width between the pressure lip seal and the shaft was developed, by employing Taguchi quality engineering and statistical design of experiment method with CAE analysis. Instead of the real experimental measurements, the influential design parameters can be performed by simulation to save cost and time. A lip seal of 38 mm diameter was optimized, as a design case, according to the contact pressure response to the Mooney-Rivlin material properties and physical dimensions in different operation environments. The current methodology is shown to be an effective design tool for a pressure lip seal.
