本文阐述轨道衡杠杆系平衡时间的计算方法。并以国內使用较多的4090型机械动态轨道衡为例,通过平衡时间的计算,分析其动态称量误差。同时与实际检测结果对照,说明杠杆系平衡时间对机械动态轨道衡的计量精度有极大影响。
This article elaborates the method of calculating the balance time of lever balance system. Taking the 4090 type mechanical dynamic railroad track scale which is widely used in China as an example, the dynamic weighing error is analyzed through the calculation of balance time. At the same time with the actual test results contrast, indicating that the lever balance time on the mechanical dynamic rail scale measurement accuracy have a great impact.
