新型便携式轨道机车车辆动态称重仪关键技术研究

Study of Key Problems in New Portable Dymanic Weigher for Railway Locomotive and Vehicle

针对目前动态轨道衡需对道床、钢轨及轨枕进行二次修改的现状,提出了一种新型便携式轨道机车车辆动态称重仪,它的主要特点是对既有线路不进行任何改动就可完成动态称重.通过对新型便携式轨道机车车辆动态称重仪中称重传感器设计及其安装、测试信号处理等关键问题的研究,表述了新型便携式轨道机车车辆动态称重仪的特点.实际运用表明测试效果良好,尤其适用于长大货物列车的称重.

The locomotive and vehicle equipments need to be tested for efficiency of dynamic weighbridge. A new portable dynamic weigher is designed for railway locomotive and vehicle without the need of changing any existing conditions roadbed, rail and sleeper. The key problems in the new portable dynamic weigher is studied, including weighing sensor design and assembly and signal testing and processing. The characteristics of the new portable dynamic weigher is also presewted. Practical application prores its effectness, especially for long vehicle weight test.
