摘要

Train startup failures affect the operation efficiency of railway lines. This study proposes a linear programming (LP) method for maximizing the locomotive traction force to enhance startup capabilities. Theoretical analysis demonstrates that the proposed strategy could fully utilize the adhesive weight of the locomotive under different locomotive structure parameters and adhesion conditions, leading to a significant enhancement in its traction startup force. A locomotive startup failure is further investigated via dynamic simulation using field monitoring data. Simulation results indicate that the proposed strategy could improve at least 6.2 % of the maximum traction startup force and promote the locomotive start successfully.
