【正文】 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。s TOR requires the rest of the principal dimensions are the same, except the length and depth, which are also required to have a small gap between these two. And because this ship nearly has no parallel middle body, it is feasible to change lines offsets through copy type transformation, and then draw lines plan using new offsets table. Second, use new lines plan and some information of parent ship to do structural calculation. Structural calculation mainly takes advantages of standard calculation to select shell plating, deck, bar, superstructure and other construction elements39。s data and new ship39。本次設(shè)計(jì)的新船滿足任務(wù)書的要求，結(jié)構(gòu)強(qiáng)度的校核也滿足文獻(xiàn)[1]的要求。其他圖也基本類似，不一一列舉。三、通過型線圖和結(jié)構(gòu)計(jì)算書以及母型資料來繪制基本結(jié)構(gòu)圖、典型橫剖面圖和橫艙壁圖。結(jié)構(gòu)計(jì)算主要是利用規(guī)范的計(jì)算選取外板、甲板、型材、上層建筑以及其他構(gòu)件的規(guī)格。又因?yàn)楸敬緵]有平行中體，所以通過型線比例的變換來改變型值是可行的，然后利用新的型值表來繪制新的型線圖，并進(jìn)行了光順與協(xié)調(diào)。50 米水泥運(yùn)輸船的結(jié)構(gòu)設(shè)計(jì)摘 要本次畢業(yè)設(shè)計(jì)是對 50m 水泥運(yùn)輸船的結(jié)構(gòu)設(shè)計(jì)，主要分為以下幾個(gè)方面來進(jìn)行設(shè)計(jì)：一、通過母型船的資料和新船的任務(wù)書來確定設(shè)計(jì)新船的型線圖。因?yàn)樾麓蝿?wù)書要求的主尺度除了船長和型深，其他都相同，而且兩者的差距很小。二、利用新的型線圖和母型船的一些資料來做結(jié)構(gòu)計(jì)算。由于本船船長小于 65 米，不用進(jìn)行總縱強(qiáng)度的計(jì)算，只需取材的剖面模數(shù)大于規(guī)范要求的最小剖面模數(shù)即可，當(dāng)然為了滿足強(qiáng)度，取材時(shí)盡量保守。以橫艙壁圖為例，利用型線圖在量取該肋位上的高度和半寬值來確定該橫艙壁的外輪廓，再利用結(jié)構(gòu)計(jì)算關(guān)于艙壁的板厚和型材規(guī)格來繪制骨架，繪制過程中參考母型船資料。四、總結(jié)設(shè)計(jì)過程中的一些經(jīng)驗(yàn)和遇到的困難，以及解決這些問題的方法，為后續(xù)結(jié)構(gòu)設(shè)計(jì)的提供經(jīng)驗(yàn)?！娟P(guān)鍵詞】 水泥運(yùn)輸船；結(jié)構(gòu)設(shè)計(jì)；規(guī)范設(shè)計(jì)；尺寸確定structure designing of 50 meters cement carrierhuang jianschool of civil engineering architecture and civil engineering，Zhejiang ocean university，zhoushan ，zhejiang 316000[Abstract] The graduation design is a structure design of 50m cement carrier, which is mainly divided into the following several aspects in design: First, confirm to design the lines plan of the new ship according to the parent ship39。s TOR.
