标准编号：ISO 21234:2022

中文名称：道路车辆 重型商用车和公共汽车 质量惯性矩测量

英文名称：Road vehicles — Heavy commercial vehicles and buses – Mass moment of inertia measurement

发布日期：2022-05

标准范围

本文件提供了确定车辆横摇、俯仰和偏航质量惯性矩（MOI）和横摇-偏航惯性积（POI）的标准方法。它适用于重型车辆，即ISO？中定义的商用车和公共汽车3833（根据ECE和EC车辆分类，M3、N2、N3、O3和O4类，最大重量超过3.5吨的卡车和拖车，以及最大重量超过5吨的公共汽车和铰接式公共汽车）。对每个单元分别进行质量惯性矩测量。

This document provides standard methods for determining a vehicle’s roll, pitch, and yaw mass moments of inertia (MOI) and roll-yaw product of inertia (POI). It applies to heavy vehicles, that is commercial vehicles and buses as defined in ISO 3833 (trucks and trailers with maximum weight above 3,5 tons and buses and articulated buses with maximum weight above 5 tons, according to ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4). Mass moment of inertia measurements are performed separately for each single unit.
