A Planning Method of Automatic Driving Control Curve for Heavy Haul Train
Heavy haul trains run with large tonnages and on complex railways. When automatic driving control curve is unreasonably planned, problems such as high impulse, speed fluctuations and frequent handle adjustments are likely to occur, which will affect driving safety. This paper proposes a method for p...

| Summary: | Heavy haul trains run with large tonnages and on complex railways. When automatic driving control curve is unreasonably planned, problems such as high impulse, speed fluctuations and frequent handle adjustments are likely to occur, which will affect driving safety. This paper proposes a method for planning automatic driving curves of heavy-haul trains. It filters out the optimal control curve in a single iteration by following the heuristic induction curve and selecting the best one according to the performance index, and iteratively updates the induction curve. The next iteration process may be output as the final manipulation curve, and the multi-objective optimization effect is achieved. Simulation results show that as the number of iterations increases, the total index of the manipulating curve is reduced by 17.99%, the stability index of the manipulating curve is reduced by 45.60%, and the train overall performance and stability are significantly improved. |
