Simulation and Experimental Study on Rollover Impact of a Bus

Taking a bus as the object, the finite element model of the bus and the numerical simulation environment of its rollover impact is established. In an LS-DYNA environment, according to the ECE R66 equivalent authentication method, the impact of bus rollover is studied by solving the presented model in numerical simulations. Energy transfer, dissipation, and the energy absorption effect of the main structure and residual space are also analyzed. By comparing impact results from the presented model with the results of a simulation analysis, the study verified the effectiveness of the presented finite element bus model. The results show that the proposed rollover impact model of a bus and the computer simulation analysis method reflect the status of real vehicle rollover impact, which has practical value in engineering applications.
