This paper develops a finite element model for crashworthiness analysis of a small-size bus. A frontal crash simulation to a rigid barrier using the developed model is performed with PAM-CRASH installed in super computer SP2. Full vehicle model is composed of 31, 982 shell elements, 599 beam elements and 42 bar elements, and 34, 204 nodes. The model uses four material mo이 such as elastic, elastic-plastic (steel), rigid and elastic-plastic (rubber) material model of PAM-CRASH. Frame and suspension system is modeled with 5275 shell elements and 5679 nodes. Body is modeled with 21633 shell elements. To show the reliability of the developed model, frontal crash test with 0mph velocity to a rigid barrier is carried out. Vehicle pulses at lower part of left and right b-pillar are measured, and deformed shapes of frame an driver seat area are photographed. Those crash test results are compared with the simulation results using the developed finite element model.
