乘员弹射保护的线性冲击程序

[中文适用范围]： 本文件的目的是根据 FMVSS226 最终规则文件（NHTSA 案卷号 NHTSA-2011-0004）中提到的 NHTSA 指南，增强用于喷射缓解测试的测试程序。乘员弹射测试的对策是使用专门为弹射缓解测试设计的无特征头模，在引导线性冲击器上使用 18 公斤质量进行测试。 SAE 不认可任何针对弹射缓解测试的特定对策。然而，该文件反映了为保持测试结果一致性而应遵循的指南。目前使用的对策的例子包括充气帘式安全气囊和夹层玻璃。测试程序如下： 确定日光开口 根据 FMVSS226 最终规则 ??2 确定目标位置 所有窗户和日光开口的目标位置 执行目标消除过程 重新构建目标 确定零平面 如果是高级玻璃@确定如果玻璃必须成为测试的一部分，并以 75mm 偏移对其进行预制动 如果是@，则遵循预破碎夹层玻璃的程序 以 5.6m/s 的速度运行测试，延迟 1.5s 以 4.4m/ 的速度运行s 延迟 6.0s [外文原描述]： The objective of this document is to enhance the test procedure that is used for ejection mitigation testing per the NHTSA guidelines as mentioned in the FMVSS226 Final Rule document (NHTSA Docket No. NHTSA-2011-0004).The countermeasure for occupant ejection testing is to be tested with an 18kg mass on a guided linear impactor using the featureless headform specifically designed for ejection mitigation testing.SAE does not endorse any particular countermeasure for ejection mitigation testing. However, the document reflects guidelines that should be followed to maintain consistency in the test results. Examples of currently used countermeasures include the Inflatable Curtain airbags and Laminated Glass.The testing procedure is as follows:1Determine the daylight opening2Identify target locations per the FMVSS226 Final Rule §5.2aTarget locations for all windows and daylight openingsbPerform the target elimination processcReconstitute the targets3Determine the zero-plane4In case of advanced glazing, determine if the glazing has to be part of the test and pre-brake it at a 75mm offsetaIf yes, than follow the procedure for pre-breaking the laminated glazing5Run the testaAt 5.6m/s with a 1.5s delaybAt 4.4m/s with a 6.0s delayCross Reference:
