중소형 버스 경량화 조립 구조 프레임

The energy crisis have faced and the environmental problems have recently raised. In this situation, the interest in light-weight frame for small & medium sized bus. this work is to develop a composite frame which will be applicable to relatively small & medium sized bus. For this frame a high efficiency and light-weight frame was designed with the proposing structural design procedure and a light composite structure frame. In the structural analysis including load case study, stress, deformation and buckling anlysis wer performed using the Finite Element Method. In its manufacturing, ther was utilized the wet lay-up and the result compared with structural experiments and structural anlysis.
