Cooperative control of wheel-rail adhesion for heavy-haul group train under condition of wheel slipping
摘要
Abstract
With the development of heavy-haul railway transportation and group operation control technology,the problem of wheel-rail adhesion has become prominent.The coordinated control technology of the heavy-haul group train and wheel-rail adhesion has become one of the important means to solve the problem of train dynamic tracking.A heavy-haul group train dynamics model was constructed.By comparing with the test results,the accuracy of the model was verified.A collaborative control method of wheel-rail adhesion and group operation was proposed and a coupling model of heavy-haul train dynamics and adhesion control and group operation control system wais established.Through co-simulation,the wheel-rail adhesion control performance and the group operation control effect under four working conditions,namely,no wheel slipping in the group train,the leading wheel slipping in the leading train locomotive,the leading wheel slipping in the following train locomotive,and all the leading wheelsets of the locomotive in the group train slipping,were analyzed.The research results are drawn as follows.Compared with the normal working condition,the motor torque has been adjusted rapidly for many times in the three working conditions.The average range of the speed difference is 0~0.42 km/h,and the average range of the train tracking distance is 0.4~1.0 m,which is far less than the corresponding threshold.As a result,wheel slipping is effectively controlled.Then,by comparing the statistical results,it is found that under the four working conditions,the results of the wheel-rail adhesion performance with wheel slipping are smaller.Meanwhile,for working condition 4,the change value of the train tracking distance is 0.40 m,and the maximum absolute value of the speed difference is 0.277 km/h.These results are both the smallest,indicating that the group operation control effect of working condition 4 is better,and the heavy-haul group train wheel-rail adhesion control method can ensure the safe operation of the trains.The coupling research on group operation control and wheel-rail adhesion control can provide an effective reference for safer train tracking distance and the exertion of train traction/braking performance.However,these findings require further validation through subsequent experimental studies.Future research should integrate train control systems for deeper investigation.关键词
