쉘형 단면을 가진 차체구조의 소재대체 경량화를 위한 개념설계 연구
A study on the conceptual design of carbodies with shell type sections for weight reduction using the material substitution technique
- 발행 : 2005.11.01
초록
In this paper is studied a theoretical approach to predict structural performances and weight reduction rates of a carbody with shell type sections in case that its materials have to be substituted. For the material substitution design of a carbody, bending, axial and twisting deformations are considered under constant stiffness and strength conditions, which utilizes some new indices derived from a structural point of view. The developed indices to measure the weight reduction by the material substitution give good guidelines on conceptual design of carbodies.
