【摘要】 在车辆发生翻滚或受到侧面碰撞的情况下,乘员有从侧窗弹出的危险。为降低这种危险性,需要改进造型、结构及材料等。该文依据2011年美国联邦机动车安全标准(FMVSS)的226法规,对于乘员侧面弹出进行模拟试验和评估。试验中,标定了碰撞器,确定碰撞目标点,对夹层侧窗玻璃进行了预破碎处理。结合一个典型的试验案例的试验结果,直观地反映了碰撞头型与侧气帘的整个碰撞过程,包括加速度、速度和位移等。结果表明:碰撞器越过0基准平面的位移小于规范限值100mm。这说明:该案例试验结果符合试验法规要求。更多还原

【Abstract】 Vehicle occupants probably eject from side windows in the accidents of vehicle rollover or side impact. Some countermeasures, such as improvement of vehicle styling, vehicle structural design and vehicle material, can be taken to mitigate the risk. Simulation tests for the occupant ejection from side windows were made and an evaluation method was built in terms of Regulation 226 by the Federal Motor Vehicle Safety Standard(FMVSS) in 2011. Some test techniques were used including calibration of impactors, determination of impact targets, and pre-breaking treatment of laminated windows. The results of an example test were presented to visually reflecting the whole process of headform impact onto the side curtain airbag in consideration of accelerations, velocities, and displacements. The results indicate that the displacement of the impactor is less than 100 mm when the impactor travels beyond the zero plane, which means that the requirements of the test regulation are well satisfied.更多还原
