Based on the investigation of the related domestic and overseas research in the domain, combined with the characteristic of all entire-bearing coach body frame, the finite element model of the bus frame was established. The stress and strain distributions are obtained in four situations： bending, turning, braking, torsion Meanwhile, the modal characteristics analysis is accomplished. The result indicated that the designed body structure satisfied the requirements of strength and stiffness criterion. The theoretic bases are given for improving design, and the analytical results are helpful to the optimized design of bus body structure.
