    Abstract: 在全球市場激烈的競爭壓力下,各國車廠無不致力於縮短產品開發時間,並推出各式各樣新型車款式,以供應多變的市場需求。是故,發展更準確快速的結構耐久安全性測試技術,以加速車輛開發時間,也越顯重要。同時,車輛零組件在真實的工作環境中,所承受負荷多屬於多軸向之變動振動負荷,且導致車輛零組件結構之疲勞損壞及失效,因此能準確評估不同應力下之疲勞壽限,對於車輛研發具有很大之助益。 本研究運用油壓伺服控制技術及遠端參數控制理論,開發一套車輛零組件之路況模擬系統,並搭配有限元素應力分析及加速耐久壽限分析理論,進行一系列隨機驅動歷程之應力測試。除了可在實驗室內精確重現車輛在實際路況下之響應,同時建立了其零組件在多軸負荷入力條件下之加速耐久疲勞壽限評估方法。研究所開發之路況模擬系統,不僅可應用於載具結構(車輛、船艦、飛航器)之入力損壞測試及疲勞壽限評估,以提供國內相關業者在設計或研發上之參考,同時,落實了本土的技術開發能力。 Road simulation testing system can reproduce the field stress and strain history of a product in the laboratory. Accelerated durability test can reduce the time and cost in developing a product by analytic and experimental approach. The purpose of this research is to develop a road simulation and accelerated durability assessment system of vehicles by using servo-hydraulic control technology and remote parameter control theory. Experiments were planned and then carried out to test the feasibility and accuracy of the developed system. The results showed that the error of root mean squares of desired history and response history was within 10%. The racetrack method and strain range editing method can compress the stress/strain history effectively.
