1Productivity
If conventional braking force distribution method is used, then the braking system is simple to operate, but the adhesion utilization rate decreases and total braking force is not sufficiently utilized due to axle load transfer
Solution Approach 1:
The braking force distribution is made dynamic by continuously calculating current axle loads based on real-time parameters (mass, acceleration, resistance, braking force, structure dimension) and adjusting the braking force allocation accordingly. This allows the system to adapt to changing axle load conditions during train operation, resolving the contradiction between simple operation and effective braking force utilization.
Solution Approach 2:
The system changes the parameter distribution by calculating axle load transfer effects and redistributing braking forces based on current axle load proportions. By modifying the braking force parameters dynamically rather than using fixed distribution, the system achieves both reliable adhesion utilization and sufficient total braking force utilization.
2Reliability
If axle load transfer is not compensated, then the calculation process is simpler, but the braking force distribution becomes inefficient and adhesion utilization decreases
Solution Approach 1:
The system performs self-service by automatically acquiring operational parameters, calculating axle load transfers, and redistributing braking forces without external intervention. This self-contained approach handles the calculation complexity internally while delivering improved adhesion utilization, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The system implements feedback by continuously monitoring operational parameters (mass, acceleration, resistance, braking force), calculating the resulting axle load transfers, and using this information to adjust braking force distribution. This closed-loop feedback mechanism ensures reliable adhesion utilization while managing calculation complexity through systematic parameter processing.

AI summary
A braking force distribution method and system for multiple marshalling train compartments are provided. The method includes: determining a current train compartment of multiple target marshalling train compartments, calculating current axel loads of axels of the current train compartment, and distributing braking forces for the axels of the current train compartment in a positive correlation manner based on the current axel loads of the axels. The braking forces of the axels are distributed by using an axel load compensation technology. A braking force generated by an axle with a small axle load is reduced according to a load-decreasing amount of the axle load, while a braking force generated by an axle with a great axle load is increased according to a load-increasing amount of the axle load, so that the braking forces generated by the axles match the axle loads.
