道路车辆.重型商用车和公共汽车.稳态侧翻阈值的计算方法

[中文适用范围]： 本文件描述了一种计算重型商用车和公共汽车稳态侧翻阈值的方法，不考虑主动控制系统的影响。 该计算方法考虑了影响侧翻阈值的主要因素，即重心高度、轮距、轮胎横向刚度以及所有影响车辆侧倾刚度的因素。 所考虑的顺应性（例如轮胎变形）对有效轨迹有相当大的影响，从而对稳态侧翻阈值有相当大的影响。 注：作为所述计算方法标准的替代方法，稳态侧翻阈值可以在测试跑道上或使用 ISO 16333 中所述的倾斜台测试进行测量。 [外文原描述]： This document describes a method for calculating steady-state rollover threshold of heavy commercial vehicles and buses, not considering the effects of active control systems. The calculation method considers the main factors that influence the rollover threshold, namely the height of centre of gravity, the track, the tyre lateral stiffness, and all factors that affect the vehicle roll stiffness. The considered compliances (e.g. tyre deformation) have a considerable influence on the effective track, and consequently on the steady-state rollover threshold. NOTE As an alternative to the described calculation method standard, the steady-state rollover threshold can be measured on a test track or with a tilt-table test as described in ISO 16333.
