In order to mitigate biomechanical injuries sustained by middle-sized children during frontal collisions of school buses, this study investigated the optimal design of intelligent airbags. Initially, a validated school bus simulation model was constructed based on sled test data. Subsequently, methods for determining head, thorax, and femur injury values for a 10-year-old THUMS dummy were established, and the model, including the school bus restraint system, THUMS dummy and intelligent airbag, was developed. Next, based on NSGA-III, the adaptive propagation factors were proposed, the Gaussian mutation operator and the evolutionary mechanism of the particle swarm optimization method were introduced, and the non-dominated sorting level was improved, thus putting forward the improved NSGA-III. Finally, the design optimization of the intelligent airbag was conducted using the improved NSGA-III to determine the optimal configuration of the airbag. The results demonstrate that the improved NSGA-III outperforms the other three state-of-the-art optimization algorithms. Under normal, 10° forward tilt, 20° forward tilt, 5° right tilt, 10° right tilt and lying sitting postures, the head injury criterion (HIC15), intracranial pressure (IP), liver pressure (LP), left and right femur forces (FL and FR, respectively), and weighted injury criterion (WICC) for middle-sized children are significantly reduced when the proportional coefficient of the gas mass-flow rate of the inflation valve, the opening pressure and opening coefficient of the deflation valves, and the installation height of the air bag are set at 1.23, 1.37×105 Pa, 2.10, and 478 mm, respectively.

为减轻校车正面碰撞中,中等身材儿童的生物力学损伤程度,开展智能气囊的优化设计研究。首先,基于台车试验,构建、验证校车仿真模型;其次,确立10岁儿童全方位人体安全模型(THUMS)假人头部、胸部与腿部损伤指标的输出方法,搭建校车-THUMS假人-智能气囊耦合模型;然后,基于第三代非支配排序遗传算法(NSGA-III),提出自适应传播因子、引入高斯变异算子、融合粒子群进化机制、改变非支配排序方法,从而提出改进型NSGA-III;最后,利用改进型NSGA-III,开展优化设计,获得气囊的最优配置。结果表明:改进型NSGA-III的性能优于其他3种著名的优化算法;正常、前倾10和20°、右倾5和10°及躺卧坐姿下,当充气阀的气体质量流率比例系数、泄气阀的开启压力和开度系数、气袋的安装点高度分别为1.23、1.37×105 Pa、2.10与478 mm时,中等身材儿童的头部伤害指标(HIC15),颅内压力(IP),肝脏压力(LP),左、右大腿力(FLFR),加权伤害指标(WICC)明显下降。

为减轻校车正面碰撞中,中等身材儿童的生物力学损伤程度,开展智能气囊的优化设计研究。首先,基于台车试验,构建、验证校车仿真模型;其次,确立10岁儿童全方位人体安全模型(THUMS)假人头部、胸部与腿部损伤指标的输出方法,搭建校车-THUMS假人-智能气囊耦合模型;然后,基于第三代非支配排序遗传算法(NSGA-III),提出自适应传播因子、引入高斯变异算子、融合粒子群进化机制、改变非支配排序方法,从而提出改进型NSGA-III;最后,利用改进型NSGA-III,开展优化设计,获得气囊的最优配置。结果表明:改进型NSGA-III的性能优于其他3种著名的优化算法;正常、前倾10和20°、右倾5和10°及躺卧坐姿下,当充气阀的气体质量流率比例系数、泄气阀的开启压力和开度系数、气袋的安装点高度分别为1.23、1.37×105 Pa、2.10与478 mm时,中等身材儿童的头部伤害指标(HIC15),颅内压力(IP),肝脏压力(LP),左、右大腿力(FLFR),加权伤害指标(WICC)明显下降。

In order to mitigate biomechanical injuries sustained by middle-sized children during frontal collisions of school buses, this study investigated the optimal design of intelligent airbags. Initially, a validated school bus simulation model was constructed based on sled test data. Subsequently, methods for determining head, thorax, and femur injury values for a 10-year-old THUMS dummy were established, and the model, including the school bus restraint system, THUMS dummy and intelligent airbag, was developed. Next, based on NSGA-III, the adaptive propagation factors were proposed, the Gaussian mutation operator and the evolutionary mechanism of the particle swarm optimization method were introduced, and the non-dominated sorting level was improved, thus putting forward the improved NSGA-III. Finally, the design optimization of the intelligent airbag was conducted using the improved NSGA-III to determine the optimal configuration of the airbag. The results demonstrate that the improved NSGA-III outperforms the other three state-of-the-art optimization algorithms. Under normal, 10° forward tilt, 20° forward tilt, 5° right tilt, 10° right tilt and lying sitting postures, the head injury criterion (HIC15), intracranial pressure (IP), liver pressure (LP), left and right femur forces (FL and FR, respectively), and weighted injury criterion (WICC) for middle-sized children are significantly reduced when the proportional coefficient of the gas mass-flow rate of the inflation valve, the opening pressure and opening coefficient of the deflation valves, and the installation height of the air bag are set at 1.23, 1.37×105 Pa, 2.10, and 478 mm, respectively.
