重庆科技学院本科生毕业设计摘要1重庆科技学院本科生毕业设计摘要I摘要本次课题是设计一个15m3的气体缓冲罐，主要包括结构设计和焊接工艺设计两大方面。在结构设计方面：首先根据设计条件确定设计文件，设计文件包括设计压力、设计温度、介质性质、材料的种类及焊接接头系数等，其次对零部件进行设计。零部件的设计包括筒体设计、封头设计、开孔补强、法兰、人孔、支座和吊耳的计算和选择。在完成以上设计后根据设计数据完成总图和零件图的绘制。在制造工艺方面：首先根据图纸完成制造工艺流程设计，其次根据流程重点对筒体、封头的制造和无损检测、水压试验等重点工序进行阐述，最后对筒体和封头纵环缝焊接工艺进行设计，并采用设计的焊接工艺进行试验、对焊接试样进行了力学性能分析。试验结果满足使用要求，证明焊接工艺是合理的，能够成功实现产品的制造。这次设计的主要意义在于锻炼了自己独立分析问题、解决问题的能力。培养了查阅资料、工作细致、认真负责、独立思考、自主创新的能力。并通过此课题的研究来进一步增强低理论知识的掌握以及研究类似问题的能力，为今后的工作打下基础。关键词：气体缓冲罐结构设计焊工艺设计工艺试验重庆科技学院本科生毕业设计ABSTRACTIIABSTRACTTheprojectistodesignagasbuffertank15m3,includingstructuraldesignandweldingtechnologyintwoareas.Instructuraldesign:First,determinethedesigndocumentsunderdesignconditions,designdocuments,includingthedesignpressureanddesigntemperature,mediumproperties,thetypesofmaterialsandweldedjointscoefficient,followedbythedesignoftheparts.Thedesigncomponentsincludecylinderdesign,headdesign,reinforcement,flanges,manholes,supportsandlugthecalculationandchoice.Afterthecompletionoftheabovedesigndataaccordingtothedesignplansandpartstocompletethetotalmapping.Inthemanufacturingprocess:First,completethemanufacturingprocessbasedondesigndrawings,thenaccordingtotheprocessfocusesonthecylinder,headofmanufacturingandnon-destructivetesting,pressuretestingandotherkeyprocessesweredescribed,andfinallyheadofthecylinderandthelongitudinalgirthweldingprocessdesignandweldingprocessusedtotestthedesignonthemechanicalpropertiesofweldedsampleswereanalyzed.Theresultsmeettherequirementtoprovethatweldingisreasonabletosuccessfulproducts.Themainsignificanceofthisdesignexerciseitsownindependentanalysisofissues,problem-solvingabilities.Developadataaccess,workismeticulous,conscientiousandresponsible,independentthinking,theabilityofindependentinnovation.Thistopicthroughresearchtofurtherenhancethelowtheoreticalknowledgeandresearchsimilarproblemstomastertheabilitytolaythefoundationforfuturework.Keywords:gasbuffertank；structuraldesign；weldingprocessdesign；technologytest重庆科技学院本科生毕业设计目录目录摘要......................................................................IABSTRACT.................................................................II1绪论..................................................................1215M3气体缓冲罐结构设计..................................................22.1设计条件..........................................................22.2设计文件...........................................................22.2.1设计压力.....................................................22.2.2设计温度.....................................................32.2.3介质性质.....................................................42.2.4材料的选择...................................................52.2.5焊接接头系数.................................................82.3零部件的设计.......................................................92...
