    Abstract
  • A finite element model of car body for a high-speed train was built, and the modal parameters were calculated by using Guyan reduction method. A system dynamics model including flexible car body was established by using multi-body dynamics software SIMPACK. The influence of car body elastic mode on riding quality was analyzed based on the model, and the vertical coupled vibration between flexible car body and bogie frame was studied. Analysis result shows that when the first vertical bending frequency of car body closes to the null nod response frequency of car body, the vertical flexible resonance of car body will happen. When the diagonal distortion frequency is higher than 9 Hz, and first vertical bending frequency is higher than 10 Hz, car body flexibility almost has no effect on riding quality. The primary suspension vertical stiffness of bogie for the train matches with the first vertical bending frequency of car body, even if frame bounce and nod frequencies coincide with the first vertical bending frequency, there will not have the flexible resonance of car body and bogie.
