이차단면모멘트 변화에 따른 볼스터 구조 설계 연구
A Study on Bolster Structure Design according to Second Moment of Area Change
- 발행 : 2011.05.26
초록
Carbody bolster must be a strong structural member of the underframe because it is in the direct line of weight transmission. On the other hand, carbody bolster is a heavy member that occupied about 20~25% in the weight of underframe. In order to reduce the weight of carbody bolster, we study the design factors such as bending stiffness, bending strength and deformation according to the change of carbody bolster's second moment of area. And we investigate the design factors of a total of 10 species of existing rail vehicles. The results of this study can be used as practicable method in designing carbody bolster in the future.
