| Abstract: | The simulation of vehicle vertical vibration is studied by finite element method. A suitable and practical calculation model is proposed. Based on numerical simulation of track irreqularities as exterior exciting source, the effects of self- vibration frequency and track irreqularity on vibration response and frame stress of vehicle is analyzed in detail. |
