Abstract A method to evaluate the effectiveness of wearable airbag protectors for motorcyclists is proposed in this work. The mitigation of thoracic injury severity in relevant accident conditions was investigated by a multimodel numerical approach. A set of impact conditions, obtained from previous work using multibody models, was used as input data to support the detailed analysis of injury risk with finite element models. The HUMOS II human model and an airbag model were validated from experimental data and coupled to evaluate the performance of the protector. Multiple frontal thoracic impact conditions were simulated on the human model by testing the airbag protector and reference simulations without any protection. A reduction on the skeletal AIS score of 1 was obtained, while the probability of sustaining severe soft tissue injuries was reduced by up to 22% with the safety device. Impact velocity and impactor shape were identified as relevant injury risk factors.

基于有限元模拟的摩托车手可穿戴安全气囊保护器评价方法

摘要 本文提出了一种评估摩托车手可穿戴安全气囊保护器有效性的方法。通过多模型数值方法研究了相关事故条件下胸部损伤严重程度的减轻。使用多体模型从以前的工作中获得的一组冲击条件被用作输入数据，以支持使用有限元模型对伤害风险进行详细分析。HUMOS II人体模型和安全气囊模型通过实验数据进行验证，并结合评估保护器的性能。通过测试安全气囊保护器和没有任何保护的参考模拟，在人体模型上模拟了多个正面胸部撞击条件。骨骼 AIS 评分降低了 1，而使用安全装置将遭受严重软组织损伤的可能性降低了 22%。撞击速度和撞击器形状被确定为相关的伤害风险因素。
