ultimate fatigue strength 中文意思是什麼
ultimate fatigue strength
解釋
極限疲勞強度-
A series of static and fatigue experiments which include lots of specimens are performed on bolted composite laminates that include different sizes, different lay orientations and different torques. dye - enhanced x - radiography is used to check the progressive damage process as evaluation techniques, which can be made nondestructively. finally, the ultimate strength and fatigue life of composite bolted joints in static tension and
層合板接頭的試驗研究考慮了多種幾何尺寸、多種鋪層及不同擰緊力矩對其靜強度及疲勞性能的影響，同時使用滲透劑增強的x射線圖象技術對靜載和疲勞損傷擴展及累積過程進行了無損檢測，並對其進行了分析探討。 -
Second, the random variables in reliability analysis of the steel rail are discussed. these random variables include the wheel load, the stiffness of the rubber pad and the bed, the temperature stress and the fatigue ultimate strength of the steel rail. and their probability distributions and parameters are discussed thoroughly
其次，對鋼軌可靠度分析中涉及的隨機變量如輪載力、軌下膠墊剛度、道床路基聯合剛度、溫度應力及鋼軌疲勞極限強度的概率分佈類型和統計特徵進行了詳細討論。 -
The using rules about the fatigue strength in " design and calculation standard for submarine structure " is worked out according to the standard that the ultimate time of submergence is less than 500
