A refined non-linear air spring model of railway vehicle model is established in this paper and the influences of different air spring failures on ride quality are studied. Results show that the orifice failure makes the air spring loses damping characteristics and deteriorates the vehicle ride quality; The failure of levelling valve has little influence on the ride quality when vehicle running on straight lines; The fracture of air spring diaphragm results in a sudden release of air, and car body secondary support disappears rapidly, excessive wheel unloading will happen and which can easily lead to derailment. In addition, the longer the leakage process, the less the influence on vehicle safety.
