标准范围

本文件适用于重型车辆，即ISO3833属于ECE和EC车辆法规M3、N2、N3、O3和O4类。这些类别适用于最大重量超过3.5？的卡车和拖车吨和最大重量超过5？的公共汽车吨。本文件描述了影响车辆稳定性和动态行为的车辆悬架运动学和顺应性（K&C）特性，并概述了常用的测量方法。这些方法适用于重型车辆。测量在单个装置上进行，通常一次测量一个或两个轴。本文件将定义或参考表征和模拟车辆悬架性能所需的关键悬架运动学和合规性参数。这些参数还提供了准静态行为的系统级描述，可级联为子系统和部件性能目标。提供了确定车辆一端悬架特性所需的悬架变量，即单轴或通过悬架配置相互关联的多轴（例如，步进梁）。不包括与前后悬架之间底盘连接有关的指标。我们将讨论一些典型的测量方法，但如何执行测量的细节不在本文件的范围内。

This document applies to heavy vehicles—that is, to commercial vehicles and buses as defined in ISO 3833—that are covered by the categories M3, N2, N3, O3, and O4 of ECE and EC vehicle regulations. These categories pertain to trucks and trailers with maximum weights above 3,5 tonnes and to buses with maximum weights above 5 tonnes.Vehicle suspension kinematic and compliance (K&C) properties that impact vehicle stability and dynamic behaviour are described in this document and common methods of measurement are outlined. These methods are applicable to heavy vehicles. The measurements are performed on a single unit and typically one or two axles at a time.This document will define or reference the key suspension kinematic and compliance parameters necessary for characterizing and simulating vehicle suspension performance. These parameters also provide system-level descriptions of quasi-static behaviour that can be cascaded into subsystem and component performance targets. The suspension variables required for determining suspension characterization of one vehicle end, i.e. for a single axle or for multiple axles inter-related through suspension configuration (for example, walking-beam), are provided. Metrics pertaining to the chassis connection between the front and rear suspensions are not included. Some typical methods of measurement will be discussed, however detail on how the measurements are executed is not within the scope of this document.
