摘　　要：针对采用基于模型的系统工程(MBSE)思想进行产品创新性设计中存在的问题,如需要额外增加大量的建模工作量、难以重用已有的企业丰富设计经验、设计方案生成效率低等,以动车组高压系统为研究对象,提出一套完整的系统架构智能高效生成流程,使能动车组高压系统智能创新设计,具体内涵为:基于MBSE思想,扩展系统建模语言元模型,构建动车组高压系统领域功能知识库和组件库,复用已有设计经验,定义一套完整可行的动车组功能到组件映射规则,设计一个高效的候选设计方案生成算法.以中国标准的250 km/h动车组高压系统为实验对象,提出的方法针对给定的动车组功能模型能够自动生成5个有效的候选系统架构,并从功能性、鲁棒性、风险性、成本、整体性能5个维度评价每种候选系统架构,提升动车组设计师系统建模效率,启发设计师创新过程.In view of the problems in product innovative design when adopting the model-based systems engineering(MBSE)ideas,such as the need for a lot of additional modeling work,the difficulty to reuse existing rich design experience,low efficiency of design scheme generation,taking high voltage system of electric motor unit(EMU)as the research object,this paper puts forward a set of complete system architecture of intelligent and efficient generation process,enables the intelligent innovation design of EMU high voltage system.The specific contents are as follows.Based on MBSE,the meta model of system modeling language(SysML)is extended.The function and components libraries of EMU high voltage system are built.By reusing existing design experience,a set of complete and feasible EMU function to the component mapping rules is defined to efficiently generate the candidate design solutions.Taking China’s standard 250 km/h EMU high voltage system as experimental object,the method for a given function of the EMU model can automatically generate a valid candidate with five system architectures.Moreover,from the five indicators of functional,robustness,risks,costs and overall performance evaluation,these candidates can improve the efficiency of EMU system modeling and inspire the innovation ability.
