Abstract
In order to study the influence of flexible body and flexible frame on vehicle running stability,four dynamic models of rigid body-rigid frame,rigid body-flexible frame,flexible body-rigid frame and flexible body-flexible frame are established and analyzed by introducing the finite element model of a domuestic EMU body and bogie frame.The results show that in the four models,the critical speed of the car body increases under the dual flexible effect of the car body and frame,and the existence of the flexible body better reflects the lateral and vertical bending vibration modes of the body,which provide a reference and basis for ensuring the good stability of the high-speed train in the whole life cycle.关键词
