  1. Then, time - variant load characteristic is decomposed and the tva load model structure is proposed to reduce the effects on the time - variation of the amplitudes of the load. finally, the group algorithm and hypothesis testing strategies are applied to solve the problem of the time - variation of the load components

    進一步對負荷特性的時變性進行分解,提出了tva負荷模型結構以消除負荷幅值大小時變性的影響,最後,採用分組演算法和假設檢驗的工程應用策略,解決了負荷組成成分的時變性問題,從而最終從一定程度上解決了負荷的時變性問題。
  2. The dissertation proposes originally the idea of decomposing the time - variant load to solve this problem. first, the time - variant load is decomposed into the time - variant load characteristic and the time - variant load model due to the modeling method. second, the multi - curve approximation method is proposed to identify the load parameters, which to a great extent, reduces the effects on the time - variation of the load model from modeling method

    針對負荷的時變性,論文首次提出了將負荷時變性分解的思想,首先將負荷的時變性分解為負荷特性的時變性和由建模方法引起的負荷模型的時變性,然後提出了多曲線擬合參數辨識方法,很大程度上消除了建模方法引起的負荷模型的時變性。
  3. 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
  4. A time - variant reliability formulation is presented in this paper to account for the effects of fatigue, corrosion and maintenance actions on the first yield reliability of midship section modulus. a probabilistic model for long - term distribution of wave - induced fatigue stress range is established. for the purpose of obtaining the performance of structure that stands random fatigue load, the concept of stress parameter and equivalent stress range are introduced

    船舶在由波浪彎矩引起的交變應力作用下,船體構件焊接點處的微小裂紋逐漸擴展;同時,隨著船齡的增加,眾多結構構件遭受腐蝕的作用;從而使船體梁剖面模數減小,船體梁承載能力衰減,船舶結構的安全性將受到相當大的影響。
  5. For ac electric arc furnace is an unbalanced, nonlinear and time variant load that produces unbalance, harmonics and interharmonics related with flicker effect. the modeling of all these aspects requires adopting a nonlinear, asymmetrical and dynamic v - i characteristic for the electric arc

    由於交流電弧爐是一種不平衡的、非線性時變負載,它產生與電壓閃變有關的不平衡、諧波和分數諧波,所有這些就需要一種非線性、不對稱的動態u ? i特性的電弧爐模型。
  6. The most difficult aspect of load modeling, which differentiates itself from other modeling problems, lies in the fact that the load is time - variant

    負荷問題作為一個區別于其它建模問題的特殊的電力系統難題,關鍵在於負荷的時變性。
