本文的主要內容是分別闡述dnv 、 gl 、 lr三種規范對底部砰擊壓力計算及底部砰擊加強結構設計的一般要求並進行一些分析比較:用dnv規范對某型船( 27000t散貨船)進行具體的底部砰擊加強結構設計,並就實際生產中產生的重載吃水狀態改輕載吃水狀態而出現的幾種設計方案進行比較,其具體結果現已用於實際生產;用直接計演算法確定砰擊壓力,再用dnv規范進行底部結構設計,對於後續船的改進均有指導意義。At first, the recent development of the simulation to cargo system of chemical ship is introduced. the significant of the research, methods and the characteristics of system simulation are also discussed. the model of cargo liquid and ballasting pipeline network is then simulated by the methods of predecessors
文章首先介紹了散裝化學品船液貨系統模擬發展的現狀,闡述了化學品船液貨系統模擬研究的意義,以及模擬的方法和特點;之後運用前人的管網有限元方法對母型船液貨、壓載管網進行模擬建模,在系統地考慮了多種因素的前提下,實現了化學品船液貨系統操作動態模擬和靜態模擬。It ) ensures effective and amazingly quick stoppage for leakage of all carriers of transportation from all walks ( tank cars for dangerous articles, pipelines, ship body and paramagnetic object shells ) under different pressure
並且對于不同行業不同壓力下的各種運輸載體(危險品運輸罐車、管道,以及艦船殼體等親磁物體外殼)的泄漏,均能進行神速有效的封堵!Thirdly, imposing pressure load on the wetted surface is a hard job because the pressure value is various and there is no regularity to fellow especially when the model is large. so it ' s very important to find a feasible automated loading approach that can be used in the fem analysis of ship structure
3 、由於向有限元模型施加壓力的時候,船體濕表面的壓力不盡相同,並且沒有規律可循,如果單元很多,那麼手工加載的效率就很低,本文開發了基於pcl的自動加載程序,提高了工作效率。Based on some discussions on the mathematic model set up for the cathodic protection potential field, a two - dimensional boundary element method ( bem ) is developed, and by using which, a study on the shielding effect resulted from some typical inner structures such as the reinforcing elements and the partition walls with man holes on distribution of potential and current density in the cathodic protection is performed. the investigated parameters which affect the shielding effect in the calculating model include : the height and thickness of the reinforcing elements, the distance between the anode and the reinforcing elements, and the diameter of man hole on the partition walls, and so on
本文在討論了陰極保護電位場問題的數學模型的基礎上,以二維邊界元法對陰極保護問題中的電位及電流密度分佈進行了模擬計算,重點對船舶壓載艙中的典型結構如加強筋、人孔等在陰極保護中所產生的屏蔽效應進行了分析和研究,通過對不同高度、厚度的擋板及不同孔徑的帶孔板所產生的屏蔽效應進行模擬計算,首次得到了一些對實際工程設計具有重要參考意義的見解。Based on the above work, the calculation formulae of nominal slamming pressure and the bearing capability of the bottom plates in the rules are modified, and the safety coefficients are evaluated referring to the target reliability specification, then the more reasonable formula of assessing the slamming strength of bottom of the bow is given
在上述工作的基礎上,對我國建造規范中原有的砰擊壓力名義值和底板承載能力名義值的計算公式進行了修正,並參照選定的目標可靠性指標求出了安全系數,給出了更為科學合理的船首底部砰擊強度定值評定公式。Vessel in ballast
有壓載的船But due to the complexity of factors influencing fatigue performance, such as wave load and pressure from cargo, the combination of different stress components, stress concentration of local structure details, mean stress and the corrosive environments, etc, there are different specifications with varying classification societies, so it will lead to the diversity of results from different fatigue assessment methods
但是,由於影響結構疲勞性能的因素十分復雜,如波浪載荷和局部的貨物壓力,各種應力成分的組合,結構的局部細節應力集中,平均應力的影響,結構分身所處的腐蝕環境等等,所以各個船級社有關的規定也不一樣,這樣必然造成各個評估方法之間的差異。High - strength rock wool board : used for various high / low temperature conditions, with good weight - bearing ability and compression - resistance, specially suitable for heat preservation and heat insulation for large ships, tanks, ovens, pipelines and other industrial facilities
