基于模块化功能分解的大型复杂构造产品造型设计方法

The Modeling Design Method for the Large Complex Products Based on Modular Functional Decomposition

目的提高大型复杂构造产品在概念设计的可控性与创意效率,探索从功能分析到创意的迭代过程。方法依据产品功能布局与各个部件的相互作用关系,分析进行功能模块化定义的条件与原理,从不同功能层进行功能分解,通过图形化的方式展开功能示意,梳理模块化概念设计的基本过程;以一款平地机产品为例,对其驾驶舱、动力舱、车身、作业模块等功能区分及布列进行规划分析,形成不同的划分组合,提供不同的造型选择,利用工业设计的创意方法,在此基础上展开外观造型创意,利用计算机辅助设计软件进行创意方案的设计表达,最后基于方案的效果进行概念化设计评价。结果完成该产品的概念设计,验证模块化功能分解的效果。结论在概念设计阶段,模块化的功能分解方法有效引导了设计团队的创意方向,为大型复杂产品提供了创意设计参考。

The work aims to improve the controllability and creative efficiency of large complex products in concept design,and to explore the iterative process from functional analysis to creativity.According to the interaction between product functional layout and various components,the conditions and principles of functional modularization definition were analyzed,functional decomposition was carried out from different functional layers,functional schematic diagram was drawn through graphical mode,and the basic process of modular concept design was combed.Taking the land leveler product as an example,the functional differentiation and layout of its cab,engine compartment,vehicle body and operation module were planned and analyzed to form different division combinations and provide different modeling choices. Based on the industrial design creative methods,the appearance modeling creativity was developed,and the computer aided design software was used to design and express the creative scheme.Finally,concept design evaluation was carried out based on the effect of the scheme.The concept design of the product was completed and the effects of modular functional decomposition were verified.In the stage of concept,the modular functional decomposition method effectively guides the creative direction of the design team and provides creative design reference for large complex products.
