对地铁转向架轮重减载率进行了介绍,并对测量静态轮重减载率的2种试验方法进行分析,阐述了均衡试验与轮重减载试验的理论依据、试验方法及评定标准,并针对后续新造车辆的静态试验提出新的建议。
This paper introduces the wheel load reduction rate of metro bogie and analyzes two kinds of test methods to measure static wheel load and derate rate. The theoretical basis, test method and evaluation standard of equalization test and wheel load deload test are expounded. And for the follow-up static test of new vehicles proposed new recommendations.
