的船體梁極限強度可靠性分析Time - variation reliability analysis based on ultimate strength of corroding ship girders
考慮腐蝕影響的船體梁極限承載能力時變可靠性分析With this understanding, this paper chooses the longitudinal strength of hull girder as the disabled mode, by the calculation of fpso, predicts the ultimate strength and effective lifetime of the hull. expected results of examples are obtained, which provide the analysis data for the further risk assessment
在此前提下，本文選擇了船體梁縱向強度失效模式，通過fpso實船計算，分析消化了理想單元法程序軟體，預報了船舶極限強度和安全有效壽命期，並用一階二次矩方法對完整受損船體的結構安全性進行了可靠性的評估，取得了預想的結果，為進一步實施綜合安全評估提供了分析數據。The analysis includes these factors - current : channel and bridge structure. it puts forward the importance and value of the study with the probability evaluation of each factor act on the navigational safety
根據可靠性理論分析橋區河段水流、航道及橋梁結構等影響船舶安全航行的因素，並對各因素影響船舶安全航行情況進行概率評估，從而提出本課題研究的重要性及意義。Abstract : the time - variant reliability analysis of ship hull girders subjected to the deg r adations of fatigue and corrosion is quantitatively carried out in this paper. th e analytical formulations are derived and simple program is compiled. as a case s tudy, the time - variant reliability of a vlcc tank is calculated. it shows that th e degradation effects of fatigue and corrosion are very important for the load - c a pacity calculation of thsip hull girders. after the second special inspection ( 10 years ), the detailed inspection should be done in order to guarantee the safety of ship navigation
文摘:定量考慮船體構件疲勞裂紋擴展和環境腐蝕對船體梁承載能力的雙重衰減因素的影響，對船體梁的時變可靠性進行了分析，列出了時變可靠性分析公式並編制了相應的計算程序.以一艘大型油船的結構可靠性為例，表明疲勞裂紋和環境腐蝕在第二個特檢年（ 10a ）之後對船體梁承載能力有顯著的影響，此時開展詳細的船體結構檢查對保證船舶營運的安全性具有重要的意義Based on the analysis of above study and the traditional experience, it concludes systemic pilot method under different conditions and also presents the guarantee measures. the bridge limits the height and breadth of channel, some measures and regulations of the safety management are necessary for the developed dependability
由於橋梁的架設限制了船舶通航的高度和寬度，因此在此提出保障船舶在橋區安全航行應建立的各種保障措施和航行安全管理規則等，以提高船舶過橋航行的安全可靠性。Time - variant reliability analysis of ship hull girders subjected to fatigue and corrosion
考慮疲勞與腐蝕影響的船體梁時變可靠性分析Since 1960s, the mechanical strength reliability and structural system reliability, whose main failure modes are fatigue and service life, has achieved a great deal of development and been applied to engineering machine, aeronautical and astronautical engineering, electric apparatus, bridges, ship, civil engineering etc. with the developing of space technology and tendency of machine towards high speed, precision, automation, one realizes the importance of mechanism reliability based on the accuracy of motion, for the errors of mechanism occurred more often than that of structure, especially in the field of aeronautical and astronautical engineering and operate system of weapon
上個世紀60年代以來，以疲勞、壽命為主要失效模式的機械強度可靠性、結構體系可靠性研究得到了很大發展，並迅速應用於工程機械、航空航天、電器設備、橋梁、船舶、土木工程等。隨著空間技術的發展以及機械的高速精密化、自動化發展，人們逐漸認識到以機構動作參數的準確可靠為主要指標的可靠性問題日益突出，因為在很多機械上機構的故障多於結構的故障，尤其是在航空航天及武器操縱系統方面。由於這些機構的運轉特性，振動可靠性的研究亦佔有突出的位置。It shows that the degradation effects of fatigue and corrosion have important influence on the safety of ship structure, especially after the ship has put into service for 10 years. and the detailed inspection should be done at this time to maintain the reliability level of ship hull girder
計算結果表明：疲勞裂紋和環境腐蝕在船舶服役10年之後對船體梁可靠性有顯著的影響，此時開展詳細的船體結構檢驗對保證船舶營運的安全性具有重要意義。The ferry - borges load combination method is applied to combine the stochastic processes of stillwater and wave bending moments, and the failure of ship hull girder occurs when the combined value of stillwater and wave bending moments exceeds the first yield bending moment
另一方面，船舶在服役期內要定期接受檢驗，一旦發現船體構件嚴重受損，則要對其進行修理。遭受損傷的構件在維修后能恢復其對船體強度的貢獻，從而提高船體梁的可靠性水平。The formulation has been applied to a bulk carrier which sails in the north atlantic ocean. furthermore, the effects of maintenance actions in increasing the reliability level of ship hull girder are analyzed
由此可見，對存在疲勞和腐蝕損傷的船體梁進行時變可靠性分析時，必須考慮維修因素的影響才能更加符合實際情況。分享友人
