Finite Element Analysis of High-Decker Bus Frontal Impact Based on ECE-Regulation No.29

Abstract:

In Thailand, according to the bus accident statistics referred to Department of Land Transport (DLT), the highest risk represents the frontal crash accidents. In case of frontal crashworthiness, the high- decker bus safety was referred to the regulation no.29 of United Nations Economic Commission for Europe (ECE-R29). In this study, the frontal impact analysis of the high-decker passenger bus structure based on ECE-R29 using Finite Element (FE) analysis was focused on. The energy absorption including to the total deformation of the frontal cabin were evaluated. Three-dimensional FE model of frontal bus structure with- and without- simple impact attenuator were created and analyzed using ANSYS/Explicit software. In accordance with the results, the average magnitude of kinetic energy in case of impact attenuator revealed the value lower than those without impact attenuator owing to absorb energy in the impact attenuator. In addition, the total deformation regarding to the safe zone of the frontal cabin in the case of with impact attenuator were lower than without impact attenuator as 75.8%. Therefore, the frontal impact attenuator should be recommended to a high-decker bus for the driver protection in the event of crash accident.
