전동차용 더블형 완충기 신뢰성 평가

Draft gear and coupling rubber pad are important components in railway vehicles. It's effects on the safety of both passengers and vehicle itself and reduce shock, vibration and noise. The shock absorber equipment is mainly consisted of the yoke, plate and rubber draft gear. The objective of the this paper is to evaluation of structure and strength for the double action draft gear in electric railway vehicles. Structure and strength analysis has been performed by use of finite element method and experimental test.
