常用车辆侧翻评价标准及其发挥的作用

The Commonly Used Vehicle Rollover Evaluation Standard and Its Role

美国NHTSA从2001年就开始规定把静态稳定系数(SSF)作为新车评测项目的一个指标,在2004年又开始引入动态试验和静态试验相结合的评价方法。伴随着这些评价指标的出台,各类汽车的SSF值均有所提高,在SUV车型中效果尤为显著。SSF作为车辆静态侧翻的一个评价指标虽然比较简单,却是一个非常直接有效的指标。介绍了美国的侧翻评价指标并展示由这些指标引起的变化,并且对国内评测的指标做出介绍,希望通过对比,国内能尽早制定出更完善的评价指标。

Since 2001, the United States NHTSA began to set the Static Stability Factor （SSF） as an indicator of the new car e- valuation project, and in 2004 began to introduce a combination of dynamic testing and static testing method. Along with the in- troduction of these evaluation indexes, the SSF value of all kinds of vehicles are improved, and the effect is particularly notable in SUV models. SSF as an evaluation index of static vehicle rollover is relatively simple, it is a very effective index. In this paper, the rollover evaluation index lists changes caused by these indicators are introduced, and the domestic evaluation index is intro- duced. Hope a more perfect evaluation index can be developed as soon as possible in China by comparison.
