Simulation and Study on Lateral Stability of Heavy Locomotive
A certain heavy locomotive dynamic model of the locomotive was established with multi-rigid-body dynamics software SIMPACK. By using AAR5, AAR4 and AAR3 track irregularities as the initial turbulence, the serpentine critical velocity of locomotive was obtained by the initial motivation method. Then,...

| Summary: | A certain heavy locomotive dynamic model of the locomotive was established with multi-rigid-body dynamics software SIMPACK. By using AAR5, AAR4 and AAR3 track irregularities as the initial turbulence, the serpentine critical velocity of locomotive was obtained by the initial motivation method. Then, based on the Australian standard and UIC 518 standards, safety operation speed of the locomotive under different track irregularity was obtained. The results showed that: The lateral stability of the locomotive could meet the requirements of safe operation; with track irregularity increasing, safety operation speed would decrease, and the lateral stability of locomotive would be worse. According to different line conditions, different simulation methods in lateral stability simulation analysis should be adopted. |
