Abstract

본 연구는 급곡선 운송시스템 산악트램 차체의 구조안전성 평가를 위한 연구이며 차체의 해석 및 실제 성능시험을 바탕으로 연구를 진행하였다. 사용된 규격은 EN 12663-1과 철도차량 기술기준 도시철도차량(노면전차) 기술기준을 이용하였으며, 유한요소해석에는 Simcenter 3D를 사용하였고, Solver는 Siemens Nastran을 사용하였다. 차체의 재질은 SMA355BP와 SS275를 사용하였고, 유한요소해석과 실제 성능시험의 결과값을 동등하게 평가하기 위하여 동일한 경계조건과 하중조건을 모사하였고 각 하중조건 별 결과를 비교 검증하였다. 하중조건 별 해석결과와 시험결과는 최대 응력값은 수직하중에서는 약 2.7%로 차이가 미미하였으나, 압축, 인장 등 다른 하중조건에서는 최대 약 36%의 차이가 발생하였다.

陡曲交通系统中山地有轨电车车体结构安全评价的有限元分析与性能试验对比研究

本研究是为了评价急曲线运输系统山岳tram车体结构安全性的研究，以车体的解释及实际性能试验为基础进行了研究。使用的规格为EN 12663-1、铁路车辆技术标准城市铁路车辆(路面电车)技术标准、Simcenter 3D分析有限元、Solver使用Siemens Nastran。车身材质采用SMA355BP和SS275，为了同等评价有限元解释和实际性能测试的结果，模拟了相同的边界条件和荷重条件，并对各荷重条件的结果进行了比较验证。不同荷重条件的解释结果和试验结果显示，在垂直荷重下，最大应力值约为2.7%，差异很小，但在压缩、拉伸等其他荷重条件下，差异最大约为36%。

期刊介绍： The Journal of the Korean Society for Railway (JKSR) launched in 1997 aims to provide a platform to exchange research information, establish and pioneer railway-related academia, and present research results that are both practical and unique. The journal covers various research results, derived from theory and experiments, on topics related to railways such as railway policy and management, railway facilities, carriage machinery, electrical signals, and track engineering. It includes research outcomes that can contribute directly to the improvement of railway technologies as well as innovative studies on fundamental areas that can be applied to railways including mechanics, electricity, civil engineering, logistics, management and so on. The themes addressed by the journal include, but not limited to the following: Rolling stock & Mechanical systems (materials, fracture, non-destructive testing, mechanics of materials and structures, design, dynamics and control, noise and vibration, heat and fluid mechanics, energy and power engineering, system engineering, reliability, maintenance, safety, etc.), Power & Signal systems (power engineering and systems, electrical devices, circuits and systems, materials and devices, control and measurement, automation, signal processing, electrical and information communication, reliability, maintenance, safety, etc.), Civil engineering for railway (structural engineering, material engineering, dynamics, seismic engineering, geotechnical engineering, measurement, geodetic survey, mapping, GIS, construction, architectural and environmental engineering, transportation engineering, etc.), Transportation policy & Operation (railway traffic planning and engineering, railway management policy, railway technology policy, railway logistics, railway operation, railway information system, railway culture, etc.).
