Song, Bo-Young,Moon, Dae-Seop,Lee, Hi Sung The Korean Society for Railway 2012 International Journal of Railway Vol.5 No.4

This study proposes a model for railway safety assessment with which the safety of whole railway system can be evaluated. The purpose of the assessment model is to generate safety indicators which quantitatively represent the degree of railway safety. Safety indicators were proposed as three indicators according to their functions; accident indicators, safety management indicators, and safety culture indicators. This paper describes the first result on the safety target which will be a key starting point toward the development of safety assessment model. It is recommended that the safety target to be composed of several sub-targets are apportioned to constituent components. It is concluded that the classification of safety target has influence on deciding components or attributes that constitute each sub-indicators; accident indicators, safety management indicators, and safety culture indicators. Based on this study, a railway safety assessment model will be developed in the following study.

강지성(Jisung Kang),김상헌(Sanghun Kim),박진규(Jinkyu Park),김연수(Yeonsu Kim) 한국철도학회 2014 한국철도학회 학술발표대회논문집 Vol.2014 No.10

국내 일부 철도차량 제작자는 ISO 9001 품질경영시스템의 적용 또는 확장을 통하여 제품의 양산품질을 전사적으로 유지, 관리하여왔으나, 이 같은 품질시스템의 도입이 제작자의 선택에 의한 것이었기 때문에 철도안전에 미치는 영향이 미미하였다. 개정된 철도안전법의 제작자승인 제도는 형식승인된 철도차량의 양산 및 판매를 위하여 제작자의 품질관리체계 구축을 강제화함으로써 철도차량 품질관리 및 안전에 대한 효과를 극대화하고자 한다. 본 연구는 품질경영시스템 표준규격의 조사·분석 및 부합화를 통하여 제작자승인 제도가 요구하는 품질관리체계가 모든 제작자에 적용 가능하고, 철도산업의 특징을 포괄하도록 그 요구사항을 도출하고자 한다. Most Korean rolling stock manufacturers have used ISO 9001 quality management system in many ways to maintain and manage the quality of their products. However, because the implementation of this system was solely dependant on to manufacturer’s judgement, it used to affect marginally on railway safety. The government’s approval system for manufacturer under the revised Railway Safety Law forces that the manufacturers shall apply the quality management system so as to ensure the safety and the quality of rolling stocks they produce. This stduy aims to draw requirements to apply all domestic rolling stock manufacturers and to cover the distinct features of the railway industry.

본 논문은 샌드위치 복합재 틸팅열차의 충돌안전도 평가 및 성능 향상방안에 대해 서술하고 있다. 차체 구조물에 적용된 샌드위치 복합재는 알루미늄 하니컴 심재와 유리섬유 및 카본/에폭시 적층 복합재 면재로 이루어져있다. 충돌해석은 외연유한 요소 해석 프로그램인 LS-DYNA3D를 이용하였다. 이때, 유한요소모델링과 충돌해석 계산시간의 절약을 위하여 3차원 유한요소모델과 1차원 등가 모델을 적용하였다. 틸팅열차의 충돌 조건은 철도안전법에 명시하고 있는 4가지 충돌사고 시나리오를 고려하여 해석을 수행하였다. 충돌해석 결과 시나리오-2를 제외한 나머지 충돌 시나리오에서 성능 요구조건을 만족하였다. 충돌 시나리오-2의 충돌안전도 요구조건을 충족하기 위하여 전두부의 적층복합재 커버와 금속프레임의 강성 향상방안을 제안하였으며, 결과적으로 충돌 시나리오-2의 요구조건을 만족하였다. This paper describes the crashworthiness evaluation and performance improvement of tilting train made of sandwich composites. The applied sandwich composite of carbody structure was composed of aluminum honeycomb core and glass/epoxy & carbon/epoxy laminate composite facesheet. Crashworthiness analysis of tilting train was carried out using explicit finite element analysis code LS-DYNA 3D. The 3D finite element model and 1D equivalent model were applied to save the finite element modeling and calculation time for crash analysis. The crash conditions of tilting train were conducted according to four crash scenarios of the Korean railway safety law. It found that the crashworthiness analysis results were satisfied with the performance requirements except the crash scenario-2. In order to meet the crashworthiness requirements for crash scenario-2, the stiffness reinforcement for the laminate composite cover and metal frames of cabmask structure was proposed. Consequentially, it has satisfied the requirement for crash scenario-2.
