动态汽车衡型式评价中关于“零点问题”的分析

Analysis of "Zero Point Problem" in Type Evaluation of Automatic Instrument for Weighing Road Vehicles in Motion

本文根据GB/T 21296.1-2020国家标准和JJG 907-2006检定规程,对动态公路车辆自动衡器型式评价中零点问题的置零准确度和温度对空载示值的影响进行分析,并针对常见问题提出相应的建议。结果表明:该方法可为型评试验以及后期动态汽车衡产品性能的改进提供参考。

In this paper, according to GB/T 21296.1-2020 national standard and JJG 907-2006 verification regulation, the zerosetting accuracy and the influence of temperature on no-load indicator value in the type evaluation of dynamic highway vehicle automatic weighing instrument are analyzed, and corresponding suggestions are put forward for common problems.The results show that this method can provide a reference for the type evaluation test and the improvement of the performance of the dynamic truck scale in the later stage.
