美国NHTSA2010年版新车评价规程的实例解析

摘要

The US National Highway Traffic Safety Administration （NHTSA） released the 2010 version of New Car Assessment Program （NCAP） in 2008, which has been used since 2011. This paper analyzes the new NHTSA-NCAP to provide technical supports and references for vehicle models of Great Wall Motor Co., Ltd or other companies who want to enter the U.S. vehicle market. The result s show that major changes take place in increasing new testing projects, applying new test dummies, optimizing associated injury criteria, assessing star rating, and so on. A model which has passed the 2011 NHTSA-NCAP star rating was used as an example to assign its star rating according to the analytical content, and was then compared to the results posted on the NHTSA official website to validate the analytical content＇s correctness. The results show that more attention should be paid to the vehicle＇s rollover resistance performance.%美国高速公路安全管理局（NHTSA）2008年发布了2010版新车评价规程（NCAP），并已于2011年正式开始实施。为对长城汽车股份有限公司或其他欲进入美国市场的车型研发提供支持，以应对NHTSA-NCAP的要求，该文对新版NHTSA-NCAP进行解析。结果表明：新版NHTSA-NCAP在试验项目增加、新款假人应用、评价指标优化、最终星级评定等方面都发生了较大变化。以某款已通过2011年NHTSA-NCAP星级评定的车型为例，按照解析内容进行星级评定，并与NHTSA官方网站发布结果进行比对，用实例的形式对解析内容进行了准确性验证。结果表明应更加重视车辆抗翻滚性能。
