도시철도차량 구조체의 소성 및 탄성모델에 따른 처짐특성 분석

This paper describes the deflection analysis method and results for elastic and plastic model of EMU(Electric Multiple Units) structural. The model has four wheels, two bolsterless bogies and one passenger coach. The wheel and bogie is modeled as a rigid body and the passenger coach is modeled as flexible bodies. Analysis methods will be introduced to consider a remanent stress of the passenger coach due to a camber of underframe. Dynamics analysis carried out to extract a dynamics stress under some camber cases.
