Abstract

At present, Metro and other urban rail transit are in the period of high-speed development opportunity. The demand of high-quality travel puts forward higher requirements for the stability and comfort of Metro vehicles. The vibration of running vehicles will do harm to passengers’ physical and mental health and ride experience and, which also affect the operation efficiency of Rail Transit. In this paper, firstly, the dynamic performance test of a type AH metro vehicle is carried out. According to GB/T5599-2019 and other standards, the hunting stability and ride quality of the vehicle under empty load and normal working condition of air spring are evaluated. The test results show that the hunting stability (safety) index of the vehicle meets the evaluation standard. The sperling index is excellent, and there is no lateral instability of bogies. Secondly, the relationship between vibration characteristics and vibration transmission of vehicle bogies is expounded.
