摘要: 对产品设计过程中的大量迭代现象,从设计方法上进行了深入分析与高度总结,提出了分析驱动设计(ALD)方法,定义了设计信息(DI)、设计活动(DA)、设计模型(DM)、设计文件(DF)和分析驱动设计流程(ALDF)等基本概念.分析驱动设计方法的核心内容是分析驱动设计流程.详细阐述了分析驱动设计流程中的设计信息和设计活动;重点讲解了分析驱动设计流程的设计活动规划方法,并给出了串行化和并行化的设计活动规划的时间计算公式.基于自动化的分析驱动设计流程对产品设计方案进行验证和优化,提高了产品设计效率和设计质量,解决了分析驱动设计方法中的部分关键技术,并以航发涡轮叶片为例验证了分析驱动设计方法.Abstract: The analysis leads design(ALD) method was advanced to summarize the key concepts and analyze the essential ideas from the iterative phenomena during the product design process. The concepts of design information(DI), design activity(DA), design model(DM), design file(DF) and analysis leads design flow(ALDF) in the ALD method were defined. As self-driven design flow, ALDF was the core concept of the ALD method. The process of establishing the ALDF was the ALD method. The design information and the design activity of the ALD flow were elaborated. The serial and parallel methods to order the design activity of the ALDF were emphasized, of which the function of time cost was given. The product design plan was optimized by the ALDF to improve the design quality and efficiency. Some key techniques of the ALD method were resolved, and the ALD method was exemplified by the structure design of the turbo-jet blade. And the conditions, the self-driven design flow, the diagram of geometry variables and performance variables of the example were given.
