摘要： A method and apparatus for adjusting wheel diameter by acquiring a current wheel diameter distribution vector; calculating similarity scores between the current wheel diameter distribution vector and known wheel diameter distribution vector clusters to determine a potential wear rate of the current wheel diameter distribution vector; calculating similarity scores between candidate target wheel diameter distribution vectors and the known wheel diameter distribution vector clusters to determine a potential wear rates of the candidate target wheel diameter distribution vectors; and selecting a target wheel diameter distribution vector from the candidate target wheel diameter distribution vectors, such that the reduction of potential wear rate achieved by switching the current wheel diameter distribution vector to the target wheel diameter distribution vector meets a predetermined condition. Future potential wear rates and the amount of grinding required during train maintenance can be optimized through changing wheel diameter distribution vectors.
