95面向生命周期的铸件结构设计方法研究

大学本科学生毕业设计（论文）中文摘要I摘要传统的铸件结构设计主要采用串行的设计方法，首先由零件结构设计人员设计出零件的基本结构，在交由铸造工艺设计人员进行铸造工艺设计和结构调整。由于零件结构设计人员对铸造工艺过程缺乏足够的认识，而铸造工艺人员又对零件结构设计的整体思想缺乏了解，彼此之间难以沟通和交流，导致铸件的设计和生产脱节。一方面浪费了大量的时间和资源，另一方面使铸件的性能难以得到保证，使铸件的设计与制造陷入尴尬的境地。本课题围绕铸件全生命周期过程，分析了传统铸件结构设计中的不足，说明了面向生命周期的铸件结构设计的重要性，综合利用各种理论知识，包括全生命周期理论、绿色制造、并行设计、面向制造的设计等，探索一种既能满足铸件结构要求，又能适应铸造过程中工艺技术要求的可行性的优化设计方法，从而达到提高铸件设计的可行性与一次性成功率的目的。关键词：铸件结构设计，全生命周期理论，绿色制造，面向制造设计，并行工程大学本科学生毕业设计（论文）ABSTRACTIIABSTRACTThetraditionalcastingstructuraldesignmainlyusestheserialdesignmethod.Thebasicstructureofthecomponentsisdesignedfirstbythecomponentsstructuredesigner,andthenhandedtothefoundrytechniquedesignersforthefoundrytechniquedesignandthestructuraladjustmentinthejunction.Thecomponentsstructuraldesignerslacktheenoughknowledgeofthefoundrytechniqueprocesswhilethefoundrytechniquedesignerscan’tunderstandtothecomponentsstructuraldesign'soverallthoughtsothatcommunicationsandexchangesbetweeneachotherbecomedifficult,thedesignandtheproductionofthecastingcomesapart.Ontheonehand,alotofwastedtimeandresources，Ontheotherhanditisdifficulttomaketheperformanceofcastingstobeassured，SothatthedesignandmanufactureofcastingsintoembarrassmentThethesisregardingthecastingentirelifecycleprocess,analyzesshortcomingsofthetraditionalcastingstructuraldesign,explainstheimportanceofthecastinglifecycle-orientedstructuraldesign,withthecomprehensiveutilizationofkindsoftheoreticalknowledge,includingtheentirelifecycletheory,thegreenmanufacturing,theconcurrentdesign,themanufacturing-orienteddesignandsoon,exploresaoptimizationmethodnotonlybeabletosatisfywiththerequirementsofthecastingstructure,butalsotosatisfywiththerequestofthemanufacturingfeasibility,inordertoenhancethecastingmanufacturethefeasibilityandtheonetimesuccessratio.Keywords:castingstructuraldesign,entirelifecycletheory,greenmanufacturing,designformanufacturing,concurrentengineering大学本科学生毕业设计（论文）目录I目录中文摘要..............................................................................................................IABSTRACT........................................................................................................II1绪论.................................................................................................................11.1课题背景......................................................................................................11.1.1全生命周期的定义.............................................................................11.1.2铸件的生命周期组成.........................................................................11.1.3面向生命周期铸件结构设计的定义....................................................11.1.4面向生命周期铸件结构设计的必要性.................................................21.2面向生命周期铸件结构设计的研究现状与进展..............................................31.2.1国内研究现状....................................................................................31.2.2国外研究现状....................................................................................41.3本课题的主要研究内容.................................................................................51.4本课题的主要研究目的及方法.......................................................................62面向生命周期铸件结构设计理论体系及相关理论基础...............72.1面向生命周期铸件结构设计理论体系的建立..................................................72.2全生命周期评估理论.....................................................................................82.2.1全生命周期评估理论的定义...............................................................82.2.2全生命周期评估的起源与发展过程....................................................92.2.3全生命周期评估的内容和方法........................................................102.3基于产品全生命周期的绿色制造(GM)...........................................................102.3.1绿色制造的认识...............................................................................102.3.2绿色制造提出的背景与必要性..........................................................112.3.3绿色制造与传统制造的区别..............................................................132.3.4绿色制造在全生命周期设计中的地位与作用.....................................142.4基于产品全生命周期的并行工程（CE）........................................................162.4.1并行工程的认识...............................................................................162.4.2并行工程提出的背景与必要性..........................................................162.4.3并行工程与传统设计的区别..............................................................162.4.4并行工程在全生命周期设计中的地位与作用.....................................18大学本科学生毕业设计（论文）目录II2.5面向制造的设计（DFM）...............................................................................202.5.1面向制造的设计的认识.....................................................................202.5.2面向制造的设计的背景与必要性.......................................................202.5.3面向制造的设计的研究内容及铸件设计评价系统..............................203面向生命周期的铸件结构设计方法...................................................233.1面向生命周期铸件结构设计方法综述...........................................................233.2铸件结构设计过程中的设计方法和思路........................................................243.3生命周期数据信息库的建立.........................................................................253.3.1面向结构设计的零件信息库建立
