Procedure to construct injury risk curves for the evaluation of road user protection in crash tests 构建碰撞试验中道路使用者保护评估伤害风险曲线的程序
发布日期: 2014-02-21
ISO/TS 18506:2014提供了为生物力学样本绘制损伤风险曲线的程序。这些样本通常经过严格审查,且大小有限,因此在绘制伤害风险曲线时需要具体步骤和检查。此外,历史上使用了几种统计方法来建立伤害风险曲线。不同方法产生的曲线可能非常接近,也可能完全不同,这取决于生物力学样本。因此,建议采用一种协商一致的方法是非常重要的。否则,纳入法规的候选伤害阈值可能会受到所用统计方法的高度影响。在统计模拟研究中比较了这些不同的方法。这项研究的结论被用来推荐生存分析。 ISO/TS 18506:2014确定了制定伤害风险曲线应遵循的步骤。 它推荐了损伤风险曲线的初步检查、统计方法和推荐过程。关于所用样本类型(尸体、动物或假人)以及所用变量和损伤严重程度的指南超出了ISO/TS 18506:2014的范围。
ISO/TS 18506:2014 provides a procedure to develop injury risk curves for biomechanical samples. These samples are often heavily censored and limited in size, such that specific steps and checks are required when developing injury risk curves. Moreover, several statistical methods were historically used to build injury risk curves. The curves resulting from the different methods could be rather close or fairly different, depending on the biomechanical samples. It is therefore of major importance to recommend a consensual method to be used. Otherwise, injury thresholds candidates to be included into regulations could be highly influenced by the statistical method used. These different methods were compared in a statistical simulation study. The conclusions of this study were used to recommend the survival analysis. ISO/TS 18506:2014 identifies steps to be followed to develop injury risk curves. It recommends preliminary checks, statistical method, and recommendation process of the injury risk curve. Guidelines on the type of the samples to be used (cadaver, animal, or dummy), as well as the variables to be used, and the injury severity level are beyond the scope of ISO/TS 18506:2014.
