Abstract Recently, the importance of the northeast economies including Russia has been growing, and according to the Eurasian initiative policy, the enhancement of transportation, logistics and connectivity between the northeast Asian countries is emerging as one of the challenges for future growth. However, due to the different vehicle systems used in each country, the railway connections between countries are not operating smoothly. Especially, the couplers of the railway cars which pass through the countries of northeast Asia including Russia have different regulations, which render their shape and characteristics incompatible. In this study, we propose a method of interconnecting the AAR type coupler used in and China and the CA-3 type coupler compatible with the Russian GOST standard, and verify that its structural safety conforms with each set of regulations. We analyze the possibilities offered by this method of interconnection by performing tests while developing materials satisfying the mechanical properties required for the freight coupler. Keywords : Coupler, Coupler adapter, Freight car, Interoperability, Variable Coupler 1. 서론 철도차량의연결기는추진력및제동력을차량간에 전달하는기능을하는안전상매우중요한구성품으로서, 최근에들어화차의장대화의필요성으로인하여, 그구조적안전성이더욱중요해지고있다. 최근에개정된 본논문은국토교통부 / 국토교통과학기술진흥원의지원으로수행되었음 (16RTRP-B ). * Corresponding Author : Jun-Ho Cheon(Leentech Corp.)

2 한국산학기술학회논문지제 19 권제 4 호, 2018 철도안전법규정에따라 2016년부터시행하는철도용품기술기준에서는안전상의중요성으로차륜, 차축과더불어연결장치를형식승인의대상으로규정하고있다 [1]. 즉, 국내에서운용되는모든철도차량은국토교통부에서정한철도차량형식승인을받아야운행할수있도록되어있다. 국내의철도차량화차의연결기는미국의 AAR(Association of American Railroads) 의규정에의한 AAR E형의연결기를주로사용하고있으며, 일부항목에대해서는국내실정에맞게관련검사및시험을통과하여야만사용할수있도록되어있다 [1,2]. 최근에러시아를포함하는동북아경제에대한중요성이대두되고있고, 유라시아이니셔티브정책에따라동북아시아간의교통, 물류, 연계성강화가미래성장동력을위한과제의하나로부상하고있다 [3]. 남북및유라시아철도연계구축을위해서는국경지역에서발생하는화물의운송을원활하게수행할수있는제도적장치뿐아니라, 서로다른차량시스템을가진철도차량의연계운행이가능하여야한다. 서로다른시스템의차량을연계운행하려는시도는유럽- 러시아간에활발하게이루어지고있는실정이나, 동북아-러시아간에는근래에들어연구가시작되고있는추세이다. 최근에표준궤 (1,435mm) 와광궤 (1,520mm) 를둘다주행할수있는궤간가변대차차량에대한연구가있었다 [4]. 특히, 화차의연결기는국내및중국은미국의 AAR 규격을기본으로한연결기를, 러시아는국가표준인 GOST(USSR State Standards) 를적용한연결기를사용하고있어, 헤드형상이서로상이하여상호간연결이불가능한실정일뿐아니라, 요구하고있는재료의화학적성질과기계적성질이상이하다 [5]. 이에, 본논문에서는국내철도용품기술기준과러시아의 GOST 규정을만족하는연결기를상호연결할수있는가변형연결기및연결기어댑터를개발하는데있어, 각국가에서제시하고있는요구사항을조사하고, 특히, 연결기에대하여요구하는기계적성질을만족하는재질을개발하는과정에서시험을통한그가능성을분석하여, 향후각국가에서안전하게사용할수있는연결기어댑터제작의발판을마련하고자한다. 다음 Fig. 1. 은국내화차의연결기결합형태를보여준다.
