To provide a method for controlling polygon wear of a wheel of a railroad transportation vehicle.SOLUTION: A method for controlling polygon wear of a wheel of a railroad transportation vehicle includes the steps of: collecting wheel information of polygon wear of a railroad transportation vehicle, performing a tracking test of a wheel and acquiring polygon wear data of the wheel; collectively designing a reinforcement parameter of a selection area of the wheel at a valley position in accordance with a wheel wear speed and a wear characteristic of a hardening reinforcement material of a tread surface of the wheel; using a hardening reinforcement technique of the tread surface of the wheel on the basis of the reinforcement parameter, performing selection area reinforcement processing to the valley position of the polygon wear of the wheel, and increasing a wear relative reinforcement processing to mountain and valley positions in the polygon wear of the wheel; and performing uniform selection area intensity processing to the tread surface of the wheel when amplitude between the mountain and the valley in the polygon wear of the wheel decreases to a fixed value to eliminate the wear of the reinforcement material of the valley position.SELECTED DRAWING: Figure 1
【課題】鉄道輸送車両の車輪のポリゴン摩耗の制御方法を提供する。【解決手段】鉄道輸送車両のポリゴン摩耗の車輪情報を収集し、車輪のポリゴン摩耗の追跡試験を行い、車輪のポリゴン摩耗データを取得するステップと、車輪摩耗速度および車輪の踏み面の焼き入れ強化材料の摩耗特性に応じて、谷位置の車輪の選択エリアの強化パラメータを合わせて設計するステップと、強化パラメータに基づいて、車輪の踏み面の選択エリアの焼き入れ強化技術を使用して、車輪のポリゴン摩耗の谷位置に対して選択エリア強化処理を行い、車輪のポリゴン摩耗における山と谷位置の摩耗相対的な速度比を増加させるステップと、車輪のポリゴン摩耗における山と谷間の振幅が一定値まで減少し、谷位置の強化材料の摩耗がなくなると、車輪の踏み面に対して均一な選択エリア強度処理を行うステップとを含む。【選択図】図1
