Rollover Simulation and Required Structural Modification of 0457 Bus

TV regulation, the equivalent method, Le., body section rollover test is selected. Also, because of impossibility of real test, the simulation results have been qualitatively compared with the existing experimental results. The extracted results show that deformation occurs mainly in the pillar-to-floor and pillar-to-roof joints, while the roof and chassis have small deformations. As the deformations in the body were greater than the standard level and the bus failed the test, suggestions were made to increase the body strength. The suggestions are based on the available capabilities and limitations of the production process.
