This paper supply one new mode clue on objectarx development technique that apply to ship design . the research includes followings : 1 . with grade optimistic method , ascertain design variable and constraint condition and objective function , set up shipping midship section ' s mathematical model . with objectarx and vc + + 6 . 0 programming languages , code cross section optimize procedure 本系統主要開發內容包括: ( 1 )利用分級優化方法確定設計變量、約束條件和目標函數,建立船舶中剖面的數學模型;利用objectarx和vc + + 6 . 0編程語言,編制橫剖面優化程序,使之符合檢驗要求。

From the study results it is showed that turret hole position near the forward of the midship has less effect to the ship girder strength and it is more reasonable using probabilty statistics method to estimate the extreme value of wave bending moment , by which the first approximate value of hull midship section modulus can be determined 研究結果表明:轉塔開孔位置在舯前附近對船體總強度影響不大;波浪彎矩極值用概率統計方法估算更為合理;船體結構剖面模數的第一近似值可用波浪彎矩設計極值等來確定。

Ken has this wonderful book that he has written with david poling , sea of glory , which tells the story of the 4 chaplains . 1943 , the torpedo struck through the water , hit the dorchester midship , spilling all the fuel oil and sinking in 25 minutes . there were only 200 survivors out of the 900 ; 700 lost their lives . later , one survivor reported that because there were the 4 chaplains just ready to leave the ship and they turned to their right and beside them were 4 men without any life jackets . 他是海的光榮the sea of glory作者之一,書中描述一九四三年,多爾切斯特船身被打穿,漏出燃油,并在25分鐘內沉沒,船上900人中只有200人生還,四位牧師在當中英勇救人,最后各人將自己的救生衣送給身旁的四人,其中一名生還者目睹四位牧者喪生

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。

During the process of the midship section design , drawing and calculating are carried through crossly ; moreover , with the development of this step , design of detailed structures would be deepened continuously . so drawing and calculating of the midship structure must be modificated again and again , until the perfect consistence between the data and graph is realized 在進行舯部結構設計時,繪圖工作與計算工作一般是交叉進行的;而且,隨著結構設計階段的發展,局部性結構設計不斷深化,舯部結構的計算和圖紙的繪制均不免要反復加以修改,直到彼此能相互準確呼應。

Fpsu is a permanent floating unit moored on the fixed turret spm , provided with raked stem , skeg , non propeller , non rudder , non - propelled and non brackets , and the living quarters utility facility are on bow , the helideck is on top of the living quarters , the process facility is on midship production deck , the flare is on stern , the bow is moored on the yoke of spm turret . it is a newly - built tanker based floating production storage unit 設有傾斜艏柱船艉設有呆木,無槳無舵,非自航,沒有艉框架,居住艙室和公共設施位于船艏直升機甲板位于居住艙室上方,處理設施位于船中部的生產甲板上,天然氣放在燃燒塔位于船艉,艏部被系固在單點系泊塔的軟鋼臂上,是新造的船型浮式生產儲油裝置。

In this paper we present in detail the process of midship section design and drawn procedure , coding shipping section plane cad application program through using microsoft visual c + + 6 . 0 , objectarx2000 programming languages and using grade optimistic method of optimization method . software design adopt windows attribute dialog box and common dialog box alternate designed means , people - computer interaction interface novelty , usableness 本文對船舶結構設計中的中橫剖面設計和繪制程序進行了研究,利用autocad軟件的二次開發功能,通過采用microsoftvisualc + + 6 . 0 、 objectarx2000編程語言和使用最優化方法中的分級優化方法,編制出了船舶剖面cad應用程序。

At last , the 3 - d finite element calculation within the midship area was carried out to analysis the transverse strength of the structural members , and the reference idea of structure optimization and lighting steel weight was submitted 最后,通過建立貨艙段三維有限元模型,對構件的橫向強度進行計算分析,并對結構優化和重量減輕提出指導性意見。

That means data and graph are divided completely . author noticed that these days , many researches about the design of midship section are focused on the scantling of the component in the preliminary design phase 本人注意到現今國內外對船舯結構設計的研究多集中在初步設計上,即定出舯剖面的框架;而在局部設計中卻鮮有作為。

This ship is built of steel , double propellers , double rudders , raked stem , transom stern , two longitudinally continuous decks and four - storey deckhouse with the engineroom located in midship , driven by diesel engines 本船原為鋼質雙槳雙舵,傾斜首柱方尾,有兩層縱通甲板和四層甲板室,機艙位于中部的柴油機客貨船。

Midship section design is a vital step among ship ' s design . this section endures most bending load , and materializes the structure of the whole ship 船舯所受彎矩最大,是全船結構主要矛盾之所在,組成了船體結構的全局性構想,因而是船舶設計的重中之重。
