Analytical Strength Evaluation of a Tilting Bogie Considering Carbody Tilting Effect

차체 틸팅효과를 고려한 틸팅대차 해석적 강도평가

This paper presents a strength evaluation of a tilling bogie frame for the Korean tilting train, The tilting bogies of the tilting train are subjected to different loading conditions compared with the bogie of the conventional railway vehicles because of the carboloy tilting on curves. We classified the load cases as two categories such as non-tilting case and tilting case. For the two categories. we have carried out structural analysis of the bogie frame to evaluate the strength of the frame. And then, we modified the shape and thickness for the weak areas of the bogie frame to ensure structural safety.
