This paper belongs to the technical field of bus passive safety. The frequent occurrence of frontal collision causes the serious destroyed buses and heavy casualties for this vehicle have great load and various occupants. So far, there are few research about the collision forms according to the event, and the safety of medium buses are always be neglected Therefore, it is necessary to discuss these problems. Taking a medium bus as the object of study, we built the finite element model accurately and used large deformation finite element analysis method and explicit dynamic analysis software LS-DYNA to simulate impact under the three conditions of 100 % overlap rate frontal impact, 40 % overlap rate offset impact and the 30° angular impact, and study on the vehicle deformation, energy absorption characteristic of acceleration and their changing regularity. After analysing some indexes as head acceleration, chest compression and pelvic acceleration, conclusion go as following: the second collision is vital to passenger’s life safety, the two point seat belt is effective to release the impact from the large acceleration and the space between the seats is also quite important for passenger’s protection.
