| Abstract: | According to the test requirements stipulated in ECE/R66 and GB/T17578-1998,a finite element model of body frame and a finite element model of body with skin for Type 6120 high-bed bus were established,then the influences of bus skin on the simulation result of rollover crash were comparatively analysed based on body column deformation and energy absorption.The simulation result shows that bus skin has a greater influence on the deformation of front and rear body columns in rollover crash simulation.Thus,th... |
