基于国六车载风速仪滑行法的试验研究

Onboard-anemometer based coastdown Experimental Research

传统车载滑行道路法基于固定式风速仪,测量条件是试验环境低风速条件,且对试验环境过程中的风速要求严格,而且风速对试验结果影响极大,会导致数据一致性不稳定;车载风速仪滑行的分析模型理论适用于高低风速环境下,试验过程中实时测量补偿车辆前部风速,对风阻和机械阻力独立分析,因此数据稳定性高。

The traditional Road-load measurement on road is based on a fixed anemometer. The measurement conditions are low wind speed conditions in the test environment, and the wind speed requirements in the test environment are strict, and the wind speed has a great influence on the test results, which leads to unstable data consistency; The analysis model theory of Onboard-anemometer based coastdown, is suitable for high and low wind speed environment. The real-time measurement compensates the front wind speed of the vehicle during the test, and the wind resistance and mechanical resistance are analyzed independently, so the data stability is high.
