Frist of all, the simple bay section frame is adopted to verify the simulation procedure, and then 6 meter bay section rollover test, simple bay section and 1.8 meter bay section pendulum test, and last full bus frame roll-over test are studied in details, including residual space, energy condition and effective plastic strains. Research results for the simulation of crash of full bus and bay section may provide a useful reference for designers. Future studies may be extended to consider full bus body structure optimization and models can be used to evaluate occupant compartment intrusion and to assess occupant protection countermeasures in various impact scenarios.
