道路车辆乘用车和挂车组合横向稳定性试验

[中文适用范围]： 本文件规定了用于乘员汽车及其拖车组合的侧向稳定性测试。适用于符合ISO 3833的乘用车以及轻型卡车和其拖车组合。该测试确定牵引车辆-拖车组合在受到定义的转向脉冲后抑制横摆振动特性的阻尼特性。 [外文原描述]： This document specifies a lateral stability test for passenger-car and trailer combinations. It is applicable to passenger cars in accordance with ISO 3833, and also to light trucks and their trailer combinations. The lateral stability test determines the damping characteristic of the yaw oscillation of such towing-vehicle–trailer combinations excited by a defined steering impulse. The combination is initially driven in a steady-state, straight-ahead driving condition. Oscillation of the vehicle is then initiated by the application of a single impulse of steering, followed by a period in which steering is held fixed and the oscillation of the combination is allowed to damp out. Testing is conducted at several constant speeds. Where non-periodic instability is of interest, a steady-state circular test is specified.
