The finite element model of bus was developed and LS – DYNA software was used to simulate structural safety of the bus when frontal impact happens. Based on the existing problems of the bus front structure, some improving methods for the bus structure were proposed, and simulation testing was conducted. Simutaion results showed that, the bus structure to satisfy safety condition. However, the collision engergy absorption of bus front structure was designed, as a results the collision acceleration was decreased, and passengers safety were increased.
