卡车变形分类

[中文适用范围]： 本 SAE 推荐做法的范围和目的是为高速公路上发生碰撞的卡车所造成的变形提供一个分类系统。该文件的适用范围仅限于中型卡车、重型卡车和铰接式组合车。 TDC 对碰撞接触变形进行分类，而不是诱发变形，因此变形被分为相当狭窄的限制或类别。然后可以在一个或多个数据库上进行碰撞变形研究，以确保所研究的数据本质上属于同一类型。尽管特定列中的字符有所不同，但本文档中保留了 SAE J224 MAR80 的许多功能。因此，每个文件必须适用于适当的车辆类型。还需要注意的是，卡车变形分类 (TDC) 并不识别特定的车辆配置和车身类型。 TDC 是一种对从事车辆安全的人员有用的表达方式，可以适当地描述碰撞损坏的卡车，并且口头和书面交流保持一致。 TDC 也是一个研究工具；然而，它并不是为用于冲击能量计算而设计的。研究界应注意不要尝试将 TDC 直接转换为复制损害所需的能量当量。该系统由七个按特定顺序排列的字母数字字符组成，形成车辆损坏的描述性组合（见图 1）。这些字符描述了主要受力方向、位置、特定区域、损坏类型和程度。各个字符位置由列号引用，以便在后续部分中提供每个分类的标识。 [外文原描述]： The scope and purpose of this SAE Recommended Practice is to provide a classification system for deformation sustained by trucks involved in collisions on the highway. Application of the document is limited to medium trucks, heavy trucks, and articulated combinations. 2xThe Truck Deformation Classification (TDC) classifies collision contact deformation, as opposed to induced deformation, so that the deformation is segregated into rather narrow limits or categories. Studies of collision deformation can then be performed on one or many data banks with assurance that data under study are of essentially the same type. 2xMany of the features of the SAE J224 MAR80 have been retained in this document, although the characters within specific columns vary. Each document must therefore be applied to the appropriate vehicle type. It is also important to note that the TDC does not identify specific vehicle configurations and body types.The TDC is an expression, useful to persons engaged in vehicle safety, to appropriately describe a collision-damaged truck with conciseness in oral and written communications. The TDC is also a research tool; however, it has not been designed for use in impact energy computation. The research community is cautioned not to attempt direct conversion calculations from the TDC to energy equivalents required to duplicate the damage.The system consists of seven alphanumeric characters arranged in a specific order to form a descriptive composite of the vehicle damage (see Figure 1 ). The characters describe the principal force direction, location, specific area, type, and extent of damage.The individual character positions are referenced by column number for identification. The definition of each classification is provided in subsequent sections.Cross Reference: 700136,810215,J224_201702
