The Analysis of Zigzagging Phenomenon after Collision between KHST and Oblique Truck

KHST와 각이 있는 트럭간의 충돌 후 틀림현상에 대한 해석

The purpose of this paper is to simulate the collision between a KHST 3D model and an oblique truck and to investigate zigzagging phenomenon. The used train model is the deformable KHST 3D model, its velocity is 110kph, and the angle of the truck is 30 degree. In order to check lateral forces between wheels and rails, the KEYWORDs that LS_DYNA provides, *RAIL_TRACK and *RAIL_TRAIN are used.
