摘要：

        研究了充气式安全带对后排乘员的保护效果。采用Madymo 软件建立某车型后排女性乘员仿真模型。并将仿真结果与试验结果进行对比，以验证仿真模型的准确性。在此模型的基础上，建立充气式安全带仿真模型并分析对后排女性假人的保护效果。从限力等级和预紧器两方面，分析充气式安全带对后排女性假人的保护效果。结果表明：充气式安全带能够很好的约束假人运动，显著降低后排假人各伤害指标以及假人头部与前排座椅的接触风险，其中胸部压缩变形量由34.8 mm 降低为29.9 mm。但在充气限力式安全带的基础上添加预紧器，会增大胸部压缩量，不利于乘员保护。

Abstract:

Madymo software was adopted to build a numerical simulation model of a constraint system for rear seat female occupant to investigate the protection effect on rear seat occupant by an airbag-belt. The simulation results were compared with the experiment results to verify the credibility of the simulation model. Based on
the numerical simulation model, an airbag-belt simulation model was established to analysis the protective effect on the rear female dummy. The protective effect of the airbag-belt was investigated in the two aspects of force limitation level and pretensioner. The results show that the airbag-belt well restrains the rear seat female dummy, and significantly reduces its damage. The airbag-belt also reduces the contact risk between the female dummy’s head and the front seat, and the thorax compression is reduced from 34.8 mm to 29.9 mm. However, the pretensioner, which was added to the airbag-belt, increases the chest compression and is not good for occupant protection.
