Mechanical Product Multi-level Conceptual Design Driven by Generalized Performance

Abstract

概念设计是机械产品设计过程的起始阶段,对产品全生命周期后续阶段的顺利开展具有重要影响,同时也存在巨大的风险。如何保证概念设计紧密围绕设计目标开展是现有研发人员亟需解决的问题。为此,本文提出广义性能驱动机械产品多层次概念设计方法,以功能、质量及约束作为设计过程驱动因素,以社会性能、技术性能及经济性能作为设计方案输出指标,分别结合实际案例对本文提出的方法、理论及技术进行验证。 本文研究内容包含以下几个方面: (1)分析广义性能组成元素并对其概念进行严格定义;在构建机械产品设计演化模型基础上,分析概念设计过程各个阶段功能、质量、约束等元素的演变情况;对设计信息进行分类,确定设计过程不同演化阶段所...As the initial and most important stage of design process for mechanical products, conceptual design has a substantial influence on the smooth implementation of other stages in the product lifecycle. Meanwhile, there are more risks in conceptual design stage compared to other stages and how to ensure that conceptual design is carried out closely around design goal is one of the issues the existing...学位:工学博士院系专业:物理与机电工程学院_机械电子工程学号:1992010015399
