Optimization Design for Seat Restraint System of School Bus in Front Impact

Youming Tang, Na Lv, Liao Yi and Hongwu Huang

Abstract:
In order to improve the two point seatbelt protection level for Middle-school student in domestic school bus, built a simulation model of occupant restraint system in school bus using multi-rigid body dynamics software MADYMO. Then analyzed the injuries of dummy’s head, thorax and leg while it was given the testing acceleration pulse and compared the results including Head Injury Criteria (HIC), thorax 3 msec acceleration and legs’ force to rules value according to standard GB24406-2012. Based on those, optimized the baseline by altering the fixed point of seat belt and the seat cushion angle. The result indicted that rising the seat angle and backward the fixed point of seat belt could decline the children occupant injury in crash and improve the protection level of school bus restraint system.
