碰撞变形分类

[中文适用范围]： 本SAE推荐实践的目的是为公路车辆事故造成的车辆变形程度分类提供基础。有必要对碰撞接触变形（与诱导变形相对）进行分类，以便将事故变形划分到相当狭窄的范围内。然后可以在一个或多个数据库中对碰撞变形进行研究，确保所研究的数据本质上是同一类型的。 七字符代码对于从事汽车安全的人员也很有用，可以在口头和书面交流中简洁地描述现场受损车辆。尽管此分类系统主要为专业团队深入调查事故而建立，其他团体也可能发现其有用。 分类系统由七个字符组成，三个数字和四个字母数字，按特定顺序排列。这些字符描述了关于变形方向、位置、区域大小和范围的细节，组合在一起形成车辆损坏的描述性组合。各个字符位置通过列号进行标识，以实现计算机存储兼容性，如图1所示。每个分类的定义在后续章节中提供。还提供了一个附录以帮助应用和解释。 [外文原描述]： The purpose and scope of this SAE Recommended Practice is to provide a basis for classification of the extent of vehicle deformation caused by vehicle accidents on the highway. It is necessary to classify collision contact deformation (as opposed to induced deformation) so that the accident deformation may be segregated into rather narrow limits. Studies of collision deformation can then be performed on one or many data banks with assurance that the data under study are of essentially the same type. 2xThe seven-character code is also an expression useful to persons engaged in automobile safety, to describe appropriately a field-damaged vehicle with conciseness in their oral and written communications. Although this classification system was established primarily for use by professional teams investigating accidents in depth, other groups may also find it useful.The classification system consists of seven characters, three numeric, and four alphameric, arranged in a specific order. The characters describe the deformation detail concerning the direction, location, size of the area, and extent which, combined together, form a descriptive composite of the vehicle damage. The individual character positions are referred to by column number for identification and computer storage compatibility as illustrated in Figure 1 . The definition of each classification is provided in subsequent sections. An appendix is also provided to assist in application and interpretation.Cross Reference:
