Abstract

As research development of seat frame is being studied actively, the total deformation of seat frame made of high tension steel plate(HTSP) is examined in this study. The seat frame made of SPFC 980 t=2mm with HTSP is tested to obtain total deformation through repeated fatigue durability tester and total deformation is analyzed by simulation under the same condition as experiment. After analyzing by comparing the results of experiment and analysis, structural stabilities of seat frame models with SPFC 780 t=2mm and SPFC 780 t=1.5mm are investigated by FEM analysis on the basis of these results. And it is considered that which model is more suitable at commercial use can be found through this study result.

시트 프레임의 연구 개발이 활발하게 진행됨에 따라 본 연구에서는 고장력강판으로 제작된 시트 프레임의 전변형량을 실험과 해석을 통하여 고찰하였다. SPFC 980 t=2mm 고장력강판으로 된 시트 프레임을 반복피로 내구 시험기를 이용하여 전변형량 실험을 한 후, 동일한 조건으로 시뮬레이션하여 전변형량을 해석하였다. 실험과 해석 결과 값을 비교 분석한 후 그 값을 토대로 SPFC 780 t=2mm와 SPFC 780 t=1.5mm으로 된 시트 프레임 모델들의 구조적 안전성을 유한 요소 해석으로서 조사하였고 본 연구 결과를 통하여 어떤 모델이 상용화하는데 더 적합한지를 알 수 있었다.
