Patent number: 10717421Abstract: 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.Type: GrantFiled: June 28, 2016Date of Patent: July 21, 2020Assignees: CRRC ZHUZHOU INSTITUTE CO., LTD., ZHUZHOU CRRC TIMES ELECTRIC CO., LTD.Inventors: Wenguang Chen, Jing Shang, Xiong Liu, Chaolu Chen, Junfeng Xu, Huishui Peng, Hua Xiao, Wei Li, Bin Zhang, Long Wang, Anhui Ji
