Of course, in order to satisfy the intensity, when you are drawing materials, it should be as large as possible. Third, design basic construction plan, model body plan and transverse bulkhead plan, by using lines plan, structure calculations and some parent ship data. Now, take drawing transverse bulkhead plan as an example, it uses lines plan on the height and width of lifting this Rib bit to ensure the periphery of transverse bulkhead. Then it uses structural calculation about thickness of plating of bulkhead and bar standard to draw skeleton, with the reference of parent ship during this time. Other plans are similar and they will not be list here one by one. Fourth, summarize some experience and difficulties met during the design process, and methods to solve these problems, in order to rise experience in structural design. The design of a new ship meet mitments requirements, and profiles checking intensity and also satisfy the document [1] requirements.【Keywords】cement carrier。包裝水泥由于紙袋破損和紙袋內(nèi)殘留水泥每年的損失在百分之五以上，散裝水泥有著運量大、損耗少、成本低、污染少等優(yōu)點，所以現(xiàn)在水泥的運輸是以散裝運輸為主。目前水泥運輸船的發(fā)展趨勢是采用的是氣力負壓吸附式卸船設(shè)備。1 總體部分 設(shè)計要求和母型資料 設(shè)計任務書主要參數(shù)：船名：50m 水泥運輸船航區(qū)：Ⅲ類航區(qū)船型：鋼質(zhì)、單甲板、單機、單槳、單舵、柴油機驅(qū)動的尾機型用途：主要裝載散裝水泥，并帶有裝卸設(shè)備，裝卸效率較高主尺度： 垂線間長 LPP 型寬 B 設(shè)計吃水 d 型深 D 船級與船籍：CCS 中國主機：6NSCM 型船用柴油機 1 臺，額定功率 900PS，額定轉(zhuǎn)速 1000r/min航速/功率儲備：不低于 船體結(jié)構(gòu)(材料\結(jié)構(gòu)形式等)：鋼質(zhì)焊接、橫骨架結(jié)構(gòu)形式設(shè)備要求：按法規(guī)和規(guī)范要求配置設(shè)計內(nèi)容：結(jié)構(gòu)規(guī)范設(shè)計：根據(jù)規(guī)范計算外板、甲板、圍板等板材的最小厚度，確定各個板材的厚度；計算各個型材的最小剖面模數(shù)確定各種型材的規(guī)格，以及各個部位的加強等。S 海水 F52~F68 4 第三壓載艙 Pamp。本設(shè)計采用放大船長的比例改變型值，每站位由母型船的 米變?yōu)樵O(shè)計船的 5 米，而由于設(shè)計吃水相同，而高度方向縮放的比例一般以設(shè)計吃水為準，因此設(shè)計船半寬和高度的型值保持不變，船長按比例放大。設(shè)計船舶主尺度：總長： 兩柱間長： 型寬： 型深： 設(shè)計吃水： 肋距： 船員 5P主甲板 ——艉樓甲板 艉樓甲板 —— 艇甲板 艇甲板 —— 駕駛甲板 駕駛甲板 —— 頂甲板 外板根據(jù)文獻[5] 船長 L 為最小型深 85%處水線總長的 96%，或沿該水線從首柱前緣至舵桿中心線的長度，取其大者。本船船底為橫骨架式時，船中部 區(qū)域內(nèi)的船底板厚度 t 應不小于按下列兩式計算所得之值(計算時肋骨間距應不小于標準間距) ： bFsEt)170(??? = （50+170）/?= bFhdst)(?? = ? =實取 t=9mm式中： s——肋骨間距，計算時取值應不小于肋骨的標準間距，肋骨標準間距為，故取 s=；d——吃水，；L——船長，50m； ——折減系數(shù)，取 =1；bFbF，其中， S 為龍骨間距，；21sE??=，計算時取不大于 ；hC——系數(shù)，見規(guī)范 。根據(jù)文獻[1] 平板龍骨的厚度不應
