T slot nut의 길이와 열하중에 의한 최대 등가 응력에 연관성이 있음을 보이고 설계 개선안을 도출하였다. 본 연구결과는 피난관제 주행로봇의 설계 과정에서 환경하중을 고려함으로써 기존 설계의 신뢰성을 확보하고 설계를 개선하는데 활용될 수 있다.","PeriodicalId":37595,"journal":{"name":"Journal of the Korean Society for Railway","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135991319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
