Analysis of Bus Structural Performance During Full Frontal Impact

This paper presents an analysis of the bus structural performance in the event of a full frontal impact (FFI), based on a computer-based crash simulation model. The vehicle model was used for FFI simulation according to real FFI test conditions. The crash simulation results were used to evaluate the overall vehicle bus structure according to the EURO NCAP (New Car Assessment Programme). The parts sensitive of bus model were confirmed. The crash analysis using finite element models showed that the most serious deformation occurred to the frontal frame of the bus structure. The bus chassis was bending in crashworthiness simulation. The energy absorbed of bus structures need to improve by optimal the frame and chassis.
