Abstract

In this study, a new dynamic interaction analysis method for tilting trains and curved track is presented. Three dimensional lumped parameter vehicle elements are used to model tilting train, and the proposed analysis technique can simulate driving direction change of vehicle, the effect of track cant, wheel-rail contact angle, and tilting angle of tilting trains, etc. The proposed method passed several basic verification tests, and it is expected that the suggested method is applicable for practical problems.

본 연구에서는 곡선부를 주행하는 틸팅열차와 궤도와의 동적상호작용을 고려한 동적해석을 수행하기 위한 해석기법을 제시하였다. 본 연구에서는 3차원 차량요소를 이용하여 틸팅열차를 모형화하였으며, 틸팅열차의 곡선부 주행시 차량의 주행방향이 크게 변화하는 상황에서 주행속도 및 원곡선 반경에 상응하는 원심력의 표현, 선로의 캔트량, 차륜-레일의 접촉각 및 열차의 틸팅각 등을 고려한 동적상호작용해석 방법을 제안하였다. 제안된 해석방법은 기본적인 검증예제들에서 만족할만한 결과를 보여주었으며, 실제적인 문제에 적용이 가능할 것으로 기대된다.
