摘要:	差速器傳動系統廣泛應用於汽車產業中，差速器能使得車輛在轉彎時，經由轉速及扭矩的分配，使得車輛能夠順利過彎。隨著科技的發展，為了因應車輛行駛過程，所遭遇的不同種類問題，差速器的發展也相繼而出。有傳統差速器、限滑差速器、托森差速器、主動式差速器，及離合式差速器等。本文基於齒輪設計軟體KISSsoft與機械系統設計模組KISSsys，並依據廠商設計之傳統差速器傳動系統建立分析模擬模型，並分析在車輛行駛中，齒輪強度、軸變形、軸強度及軸承壽命等參數，評估以上參數是否達到廠商要求及安全規範，並給與改善及建議。此外，利用多體動力學分析軟體ADAMS，模擬車輛行駛中所遇之情形，並將動力分析結果回饋至機械系統設計模組KISSsys中，探討行駛中可能遭遇的各種突發情形對於齒輪強度及軸承壽命之影響。;The differential transmission system are widely used in the vehicle industry, Due to the speed and torque distribution of the differential, the vehicle can turn more smoothly. With the development of science and technology, in order to cope with the different types of encountered situations during driving, the development of differentials has also been proposed one after another. There are traditional differentials, limited slip differential, Torsen differentials, active differentials, and clutch differentials, etc. Therefore, this study aims to establilsh KISSsoft analysis models for a traditional differential system designed by the cooperation vehicle manufacturer, to analyze and evaluate whether the gear strength, shaft deformation and bearing life meet the design requirements and safety specifications. In addition, the dynamic responses simulated by the established multi-body dynamics (MBD) analysis model under the impact of unexpected situations are imported into KISSsoft model to analyze the effects on gear strength and bearing life.
