Reliability Evaluation of Air Spring for Railway Vehicle

Air spring system in railway vehicles primarily ensure the air suspension of the vehicle body. The low natural frequency ensures a comfortable ride and an invariably good stiffness. In this paper, the characteristics and durability test was conducted in laboratory by using servo-hydraulic fatigue testing system to reliability evaluation of air spring for electric railway vehicle. The experimental results show that the characteristics and durability of domestic development productions are obtained the good results.
