METHOD AND APPARATUS FOR ADJUSTING WHEEL DIAMETER

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for adjusting a wheel diameter.

SOLUTION: The method includes: a step for acquiring an actual wheel diameter distribution vector; a step for calculating a similarity score between the actual wheel diameter distribution vector and a known wheel diameter distribution vector cluster in order to determine a potential wear rate of the actual wheel diameter distribution vector; a step for calculating a similarity score between candidate target wheel diameter distribution vectors and the known wheel diameter distribution vector cluster in order to determine the potential wear rate of the candidate target wheel diameter distribution vectors; and a step for selecting a target wheel diameter distribution vector from the candidate target wheel diameter distribution vectors so that the reduction of the potential wear rate obtained by switching the actual wheel diameter distribution vector to the target wheel diameter distribution vector is matched with a predetermined condition. By a resolution method of the invention, a future potential wear rate and grinding quantity necessary for maintenance of a train can be optimized through a change in wheel diameter distribution vectors.
