Road vehicles - Heavy commercial vehicles and buses – Mass moment of inertia measurementstandard by International Organization for Standardization, 04/30/2022
standard by International Organization for Standardization, 04/30/2022
This document provides standard methods for determining a vehicles 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.
