Abstract

This paper describes the evaluation of structural performance test and finite element analysis to verify the design of Bimodal Tram made of sandwich composites. The sandwich composite applied to vehicle structure was composed of a aluminum honeycomb core and WR580/NF4000 glass fabric/epoxy laminate composite facesheet. The load tests of vehicle structure were conducted for vertical load, compressive load, torsion and modal analysis according to JlS E 7105. The structural Integrity of vehicle was evaluated by the measurement of displacement, stress and natural frequency obtained from dial gauge, strain gauge and gravity sensor, respectively. And finite element analysis using ANSYS v11.0 was done to compare with structural test. The results showed that the displacement, stress and natural frequency were in an good agreement with those of structural analysis using the proposed finite element models.

논문은 샌드위치 복합재가 적용된 바이모달 트램의 설계검증을 위한 구조 성능 시험과 유한요소 해석에 대해 기술하였다. 차체 구조물에 적용된 샌드위치 복합재는 알루미늄 하니컴 심재와 WR580/NF4000 유리섬유/애폭시 면재로 구성되었다. 이때, 차체 구조물의 구조 시험은 JIS E 7105 규정에 따라 수직하중, 압축하중, 비틀림 및 고유진동수 시험이 각각 수행되었다. 그리고 다이얼게이지, 스트레인게이지, 가속도 센서를 통해 얻어진 처짐, 응력, 고유전동수 결과에 따른 구조 안전성을 평가하였다. 그리고 Ansys v11.0을 이용하여 유한요소해석을 수행하였고, 구조 시험 결과와 비교하였다. 구조 시험 결과는 제안된 유한요소 모델을 사용한 구조 해석 결과와 처침, 응력, 고유진동수가 비교적 잘 일치함을 확인하였다.
