船舶設(shè)計(jì)簡(jiǎn)介外文翻譯-其他專(zhuān)業(yè)(文件)
【正文】 。在此階段，交換僅限于設(shè)計(jì)工作于技術(shù)工人之間，也就是說(shuō)，一個(gè)設(shè)計(jì)工程師的設(shè)計(jì)不再由任何其他工程師進(jìn)行評(píng)判、調(diào)整或修改。 d 詳細(xì)設(shè)計(jì) 船舶設(shè)計(jì)的最后階段是繪制詳細(xì)的施工圖。這一階段更加準(zhǔn)確地描繪船舶特征，如基于一套光滑線組成的船體線型，基于模型試驗(yàn)的主機(jī)功率匹配，船舶耐波性與操縱性，螺旋 槳數(shù)量對(duì)型線的影響，結(jié)構(gòu)細(xì)節(jié)，不同類(lèi)型鋼材的使用，肋骨間距和形式等。一些控制 參數(shù)如船長(zhǎng)，船寬，功率和載重量，在該階段完成之后不宜再變更。這包括基于曲線、公式經(jīng)驗(yàn)而進(jìn)行的空船重量初步估算。一套良好的合同圖紙和詳細(xì)說(shuō)明書(shū)應(yīng)當(dāng)是非常清晰和詳細(xì)的，以避免高成本的偶然性項(xiàng)目，并使投標(biāo)者不出現(xiàn)模糊不請(qǐng)的或不充分的描述。進(jìn)一步講，基本設(shè)計(jì)還包括校核和修改，以滿足貨物裝卸能力，居位艙，客房設(shè)施，分艙和穩(wěn)性標(biāo)準(zhǔn)，干舷和噸位測(cè)量，所有這些都是將船舶當(dāng)成運(yùn)輸、工業(yè)化或服務(wù)系統(tǒng)的一部分。 s preliminary design further refines the major ship characteristics affecting cost and performance. Certain controlling factors such as length, beam c. Contract design The contract design stage yields a set of plans and specifications which form an integral part of the shipbuilding contract document. It enpasses one or more loops around the design spiral, thereby further refining the preliminary 2 design. This stage delineates more precisely such features as hull form based on a faired set of lines, powering based on model testing, sea keeping and maneuvering characteristics, the effect of number of propellers on hull form, structural details, use of different types of steel, spacing and type of frames. Paramount , among the contract design features, is a weight and center of gravity estimate taking into account the location and weight of each major item in the ship. The final ge
