摘要: | 由於輪內馬達驅動系統之發展,突顯出簧下質量對於車輛動態性能之影響。本論文主要發展了一雙A臂式懸吊系統之非線性模型,並利用前人所發展之麥花臣式懸吊系統模型及一般普遍使用的四分之一車輛簡化模型進行比較與驗證。藉由本文所發展之雙A臂式懸吊系統模型,針對簧下質量之效應進行電腦輔助分析,以探討簧下質量對於車輛乘坐舒適性、操控穩定性及懸吊設計限制等車輛懸吊動態性能之影響。最後,針對雙A臂式懸吊系統之主要設計參數進行分析,觀察其對於車輛動態性能之影響,以尋求懸吊系統設計與調整之基本規則。本研究針對簧下質量所探討之影響與懸吊參數分析所獲得之結果,應有助益於車輛懸吊系統之設計。 Because of the development of the in-wheel-drive system, the effect of unsprung mass to the vehicle dynamics thus becomes more significant. In this study, a nonlinear model of double wishbone suspension system is developed. The model is compared to the already developed Macpherson suspension model and the conventional quarter car simplified model. The verification is thus done. Using the model developed in this study, the effect of unsprung mass could be analyzed numerically. The influence to the performance index, such as ride comfort, handling stability and design constraint on available suspension stroke, would be examined. Finally, the design parameters of the double wishbone suspension system are analyzed to find out their effect to vehicle dynamics performance index. It would be helpful to the design of a suspension system while the unsprung mass effect is significant, and must be considered deliberately. |
