重型商用车辆与公共汽车.稳态倾翻阈.倾斜台试验方法

[中文适用范围]： 本国际标准规定了估算重型商用车或客车稳态侧翻阈值的倾斜台试验方法，即试验车辆在稳态转弯时不侧翻时能够承受的最大横向加速度。 它适用于完整的滚动单元/滚动耦合车辆单元的组合——例如单体车辆、牵引车-半挂车组合、铰接式客车、全挂车、B-列车组合——商用车、商用车组合、公共汽车或铰接式公共汽车根据 ISO 3833 以及 ECE 和 EC 车辆法规类别 M3、N2、N3、O3 和 O4 的定义（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）。 它不包括瞬态、振动或动态翻滚情况；也没有考虑动态稳定控制系统的影响。 此外，随着产生侧翻所需的倾斜角度的增加，由测试方法提供的稳态侧翻阈值的估计的质量降低。 即便如此，具有高侧翻阈值的重型车辆的结果可用于比较其相对稳态侧倾稳定性。 注：有关指定测试方法的进一步限制，请参见附录 B。 [外文原描述]： ISO 16333:2011 specifies a tilt-table test method for estimating the steady-state rollover threshold of a heavy commercial vehicle or bus, i.e. the maximum lateral acceleration that the test vehicle could sustain in steady-state turning without rolling over. ISO 16333:2011 is applicable to complete roll units/combinations of roll-coupled vehicle units, e.g. single-unit vehicles, tractor semitrailer combinations, articulated buses, full trailers, B-train combinations, of commercial vehicles, commercial vehicle combinations, buses or articulated buses as defined in ISO 3833, and under Categories M3, N2, N3, O3 and O4 of ECE and EC vehicle regulations (trucks and trailers with maximum weights above 3,5 t and buses and articulated buses with maximum weights above 5 t). ISO 16333:2011 does not cover transient, vibratory or dynamic rollover situations; nor does it consider the influences of dynamic stability control systems. Furthermore, the quality of the estimate of the steady-state rollover threshold provided by the test method decreases as the tilt angle required to produce rollover increases. Even so, the results for heavy vehicles with high rollover thresholds can be used for comparing their relative steady-state roll stability.
