一、问题的提出动态电子轨道衡是大批量原材物料计量的现代化设备.大家知道,动态电子轨道衡的计量精度是与车速的大小及匀速性有着密切关系的.当列车以3～7公里/小时的速度匀速通过电子轨道衡的台面时,其计量精度是符合国家有关动态电子轨道衡检定规程规定的.而当列车超速或速度严重不匀时,由于振动加剧,计量精度就会降低,从而使计量数据失效.为此,必须严格考核列车进入电子轨道衡台面的速度及匀速
First, the issue put forward Dynamic electronic track scale is a large quantity of raw materials measurement of modern equipment.As we all know, dynamic electronic railroad scale measurement accuracy and speed and size are consistent with the speed.When the train to 3 ~ 7 km / h Of the speed uniform through the electronic rail scale table, the measurement accuracy is in line with national regulations related to dynamic electronic track scale verification rules.While the train speeding or serious uneven speed, due to increased vibration, measurement accuracy will be reduced, so that the measurement data Failure.To this end, we must strictly assess the train into the electronic track scale surface speed and uniform
