Demand-driven Design Method for Rail Transit Vehicles

[目的]针对不同的产品设计多样化需求,为了基于客户需求快速设计、制造出满足要求的高速列车,有必要对基于需求驱动的轨道交通车辆设计方法进行研究。[方法]通过收集、归类和总结轨道交通车辆的各种需求,并对需求进行梳理、匹配、参数化等操作,建立了需求数据库。针对轨道交通车辆的个性化特征,将个性化需求逐渐分解到轨道交通车辆各层级及组份中,形成需求模型。采用直接映射、函数映射、知识映射等规则构建需求与指标之间的映射规则。[结果及结论]本文所提基于需求驱动的轨道交通车辆设计方法,能够将所收集到的轨道交通车辆需求进行结构化、规范化、属性化的定义和归类,形成不同层级、不同属性及不同车型的需求数据,基于客户指定需求提出相应的轨道交通车辆设计需求,再映射到轨道交通车辆技术指标,最终获得一组轨道交通车辆快速设计数据。

[Objective]To address the diverse design needs of different products and meet customer requirements for quick design and manufacture of high-speed trains,it is necessary to study demand-driven design methods for rail transit vehicles.[Method]By collecting,classifying,and summarizing various demands for rail transit vehicles,and performing operations such as sorting,matching,and parameterizing these demands,a demand database is established.For the personalized characteristics of rail transit vehicles,personalized demands are gradually decomposed into various levels and components of the vehicles,forming a demand model.Mapping rules between demands and indicators are constructed using direct mapping,function mapping,and knowledge mapping.[Result&Conclusion]The proposed demand-driven design method for rail transit vehicles can define and classify the collected demands for rail transit vehicles structurally,normatively,and attributively,forming demand data of different levels,attributes,and vehicle models.Based on customer-specified demands,corresponding rail transit vehicle demands are proposed,which are then mapped to technical indicators of the rail transit vehicles,ultimately obtaining a set of rapid design data for rail transit vehicles.
