Abstract

This work dealt with structural safety analysis about sandwich composite structure of automotive floor board. In this work, structural design and analysis of sandwich composite structure for automobile floor board were performed. Firstly, structural design requirement of automobile floor board was investigated. After structural design, the structural analysis of the automobile floor board were performed by the finite element analysis method. It was performed that the stress and displacement analysis at the applied load condition. After structural test of target structure, structural test results were compared with analysis results. Through the structural analysis, it was confirmed that the designed floor board structure is safety.

본 연구는 자동차 바닥 구조로 적용된 샌드위치 복합재 구조의 안전성 해석에 관한 연구이다. 본 연구에서 샌드위치 복합재 구조 적용 자동차 바닥의 구조 설계 및 해석을 수행하였다. 1차적으로 자동차 바닥 구조의 구조 설계 요구 조건이 분석되었다. 구조 설계 이후 유한 요소 해석 기법을 활용하여 자동차 바닥 구조의 구조 해석이 수행되었다. 적용 하중 조건에서 응력 및 변위 해석이 수행되었다. 최종바닥 구조의 구조 시험을 수행한 후 해석 결과와 비교하였다. 구조 해석을 통해 설계된 샌드위치 복합재 바닥 구조는 안전한 것으로 확인되었다.
