【摘要】：船舶穩(wěn)性是船舶在設計過程中的必要考慮因素,對船舶穩(wěn)性及其規(guī)范的研究也是船舶領域研究的重點。目前,世界范圍內(nèi)通用的穩(wěn)性檢驗規(guī)范是《2008年完整穩(wěn)性規(guī)范》,然而,隨著不斷發(fā)生的船舶穩(wěn)性失效事故也引發(fā)人們對規(guī)范適用性的思考�；陟o力學及經(jīng)驗公式的穩(wěn)性規(guī)范已經(jīng)不能覆蓋現(xiàn)有船型如客滾船,也不能作為船舶在波浪中的穩(wěn)性檢驗衡準。另一方面,IMO及各專家學者認為應將船舶水動力學應用到船舶穩(wěn)性衡準中,即船舶穩(wěn)性衡準應涉及船舶在波浪中的穩(wěn)性問題�；谝陨蟽牲c,IMO正在制定第二代完整穩(wěn)性衡準,純穩(wěn)性喪失是其中五大穩(wěn)性失效模式之一,對純穩(wěn)性喪失薄弱性衡準的研究可以為第二代完整穩(wěn)性衡準的制定提供依據(jù),并起到一定的推動作用。 本文基于純穩(wěn)性喪失薄弱性衡準草案的程序開發(fā)及樣船計算,主要內(nèi)容為： (1)初穩(wěn)性高GM和復原力臂GZ求解介紹。簡要介紹靜水及波浪中復原力臂和初穩(wěn)性高的求解方法,并對復原力臂曲線的特征值做介紹。 (2)波浪參數(shù)確定：介紹了基于北大西洋海浪譜將隨機波轉(zhuǎn)換為規(guī)則波的兩種不同方法進行介紹。主要是規(guī)則波中波長和波高因素的確定。 (3)基于純穩(wěn)性喪失薄弱性衡準草案的程序開發(fā)驗證：由于船舶在波浪中回復力損失是引發(fā)純穩(wěn)性喪失失效模式的關鍵因素,所以首先對其復原力變化產(chǎn)生影響的因素進行介紹。其次,對純穩(wěn)性喪失發(fā)生過程及其薄弱性衡準方法進行介紹,并利用Visual Basic6.0語言進行相應程序開發(fā)。最后,以C11集裝箱船為例利用程序進行計算,并將計算結(jié)果與702所進行對比,從而對程序的正確性進行驗證。 (4)利用程序進行的樣船計算：以2艘漁政船作為樣船,利用程序進行實船計算,并對樣船計算結(jié)果進行分析。
[Abstract]:Ship stability is a necessary factor in the design of ships, and the study of ship stability and its specifications is also the focus of the research in the field of ships. At present, the universal stability inspection code is the complete Stability Code of 2008. However, with the continuous occurrence of ship stability failure accidents, people also think about the applicability of the code. The stability codes based on statics and empirical formulas can no longer cover existing ship forms such as passenger ro / ro ships and can not be used as the stability test of ships in waves. On the other hand, IMO and various experts and scholars believe that ship hydrodynamics should be applied to ship stability balance, that is, ship stability criterion should involve ship stability in waves. Based on the above two points, IMO is making the second generation complete stability criterion, and the loss of pure stability is one of the five failure modes. The study on the weakness of pure stability loss can provide the basis for the formulation of the second generation complete stability criterion. And play a certain role in promoting. This paper is based on the program development and the calculation of the sample ship based on the draft of pure stability loss weakness leveling. The main contents are as follows: (1) the solution of the initial stability high GM and the restoring arm GZ are introduced. This paper briefly introduces the solution method of restoring arm and high initial stability in static water and wave. The eigenvalues of the restoring arm curve are introduced. (2) Wave parameter determination: two different methods of converting random wave to regular wave based on North Atlantic wave spectrum are introduced. It is mainly about the determination of wave length and wave height in regular wave. (3) Development and verification of the procedure based on the draft of pure stability loss weakness leveling: because the loss of ship's return force in wave is the key factor to cause the failure mode of pure stability loss, So first of all, the factors that influence the change of resilience are introduced. Secondly, the process of pure stability loss and the method of weak balance are introduced, and the corresponding program is developed by Visual basic 6.0 language. Finally, taking C11 container ship as an example, the program is used to calculate, and the result is compared with 702, so the correctness of the program is verified. (4) the calculation of the sample ship carried out by the program: take two fishing administration ships as the sample ship. The program is used to calculate the real ship and the result of the sample ship is analyzed.
