    • Abstract:
      The bogie is an important guarantee for the safe operation of the train, and the primary suspension device is an important component of the bogie, connecting the wheel axle device and the frame, transmitting the vertical force of the train, absorbing the vertical vibration energy during train operation, and ensuring the smoothness of train operation. As an important form of suspension system for subway vehicles, conical rubber springs are prone to dynamic creep under repeated vertical forces during long-term use. This article adopts the method of real vehicle testing to regularly measure the height of a series of rubber springs on two selected test trains for a period of 39 months. The dynamic creep of the conical rubber springs is found to be between 0.17-0.18 cm/103 km. This conclusion provides a reference for railway departments to choose the timing of cushion work and determine the reserved amount for height adjustment, further ensuring the safety of train operation.
