Abstract

In order to study the student occupant injury risk of school bus at the driving speed exceeding 30km/h, the numerical simulation model of children occupant restraint system of school bus was built using software LS-DYNA 3D. According to the China regulation of GB24406-2012, the model was loaded with four acceleration pluses respectively, so as to compare the Head Injury Criterion (HIC), thorax 3ms acceleration and femur force in different driving speed. The results show that, the student occupant's HIC rises significantly along with the increase of driving speed. The student occupant's thorax injury grows lightly with the increase of driving speed when the speed is lower than 48km/h, but grows rapidly once the speed exceeds 48km/h. The driving speed range of 30-50km/h is relatively appropriate for the middle school student occupant's safety.
