摘　　要：变型设计是实现高速列车转向架定制设计的关键技术之一。针对当前高速列车转向架变型设计过程中缺乏有效的知识管理与重用方法,进而影响转向架设计效率与质量的问题,提出高速列车转向架变型设计知识推送系统构建与应用框架,分析高速列车转向架变型设计知识,利用知识图谱技术实现转向架变型设计知识的结构化表达与存储。基于此,提出知识图谱嵌入与路径推理相结合的知识推理技术,匹配并筛选出与当前转向架变型设计活动相关联的设计知识;开发高速列车转向架变型设计知识推送系统,实现嵌入设计活动的知识主动推送,并以高速列车构架变型设计为例,验证该系统能够为设计人员提供一个集成的知识支持环境,其具备一定的可行性与工程应用价值。Variant design is one of the key technologies to realize the customization design of high-speed train’s bogies.In view of the lack of effective knowledge management and reuse methods in the process of variant design of high-speed train’s bogies,which affects the efficiency and quality of bogie design,the construction and application framework of knowledge push system for variant design of high-speed train’s bogies is proposed.The variant design knowledge of high-speed train’s bogies is analyzed,and the structured expression and storage of variant design knowledge of bogies is realized by using knowledge graph technology.Based on this,a knowledge reasoning technology combining knowledge graph embedding and path reasoning is proposed to match and screen the design knowledge associated with the current bogie variant design activities.The knowledge push system for variant design of high-speed train’s bogie is developed to realize the active push of knowledge embedded in design activities.And through the case study on the variant design of high-speed train’s frame,it is verified that the system can provide an integrated knowledge support environment for designers,which has certain feasibility and engineering application value.
