道岔是使列车在不同轨道之间进行转换的关键铁路设备,为动态分析其研究演进路径,以Web of Science核心数据库1986年-2023年共175篇文献为研究对象,运用CiteSpace软件的可视化分析功能,对文献数量时序分布,作者、机构和国家(地区)的合作网络,期刊共被引,关键词共现等进行知识图谱可视化分析.结果表明:道岔领域发文数量稳步上升,中国是发文量最多的国家,核心研究力量主要来自高校.中国、英国、美国、瑞典、荷兰在研究领域均表现活跃.发文期刊质量较高平均影响因子为5.35,不同阶段的研究侧重点有所不同,有"轨道几何学""故障诊断""贝叶斯网络""远程状态监测""柔性轮对""建模""动态交互""故障分析"等.这些研究成果可为国内外道岔研究提供参考依据.
Analysis of Knowledge Graph on Railway Switch Equipment Research Based on CiteSpace
Turnouts are critical railway equipment that enables trains to switch between different tracks.To dynamically analyze its research evolution path,a total of 175 documents from the Web of Science core database between 1986 and 2023 were selected as the research objects.The visual analysis function of CiteSpace software was employed to conduct a knowledge map visualization analysis of the temporal distribution of document quantity,the collaboration networks of authors,institutions,and countries,the co-citation of journals,and the co-occurrence of keywords.The results show that the number of publications in the field of turnouts has steadily increased,with China being the country with the highest number of publications.The core research strength mainly comes from universities.China,the United Kingdom,the United States,Sweden,and the Netherlands are all active in the research field.The quality of the published journals is relatively high,with an average impact factor of 5.35.The research focus of different stages is different,including"orbit geometry","fault diagnosis""Bayesian network""remote state monitoring""flexible wheelset","modeling""dynamic interaction""fault analysis"and so on.These research results can provide reference for domestic and international turnout research.
