To provide a method by which a railway vehicle truck can easily evaluate a track state while the truck traveling on the railway track.SOLUTION: A method in this invention comprises the steps of: installing respective non-contact distance meters 5a, 5b in a pair of left and right axle boxes 41a, 41b supporting a front wheel shaft of a pair of front and rear wheel shafts 1, 2 which a railway vehicle truck 100 traveling on a railway vehicle track has; measuring a distance L to a side face of a head part R11 of an outer track side rail R1 of a curved track using the distance meter 5a positioned in an outer track side among the respective distance meters 5a, 5b fitted to the pair of left and right axle boxes 41a, 41b during a truck 100 travels along the curved track; and evaluating a wearing WE of a side face of the head part R11 of the outer track side rail R1 of the curved track, based on a difference of the measured distance L and a reference distance L0 when the wearing WE of the side face of the head part R11 of the outer track side rail R1 does not occur.SELECTED DRAWING: Figure 1
【課題】鉄道車両用台車が鉄道車両用軌道を走行しながら軌道の状態を容易に評価可能な方法等を提供する。【解決手段】本発明に係る方法は、鉄道車両用軌道を走行する鉄道車両用台車100が具備する前後一対の輪軸1、2のうち前側輪軸1を支持する左右一対の軸箱41a、41bにそれぞれ非接触式の距離計5a、5bを取り付けるステップと、左右一対の軸箱41a、41bにそれぞれ取り付けられた各距離計5a、5bのうち、台車100が曲線軌道を走行する際の外軌側に位置する距離計5aで、曲線軌道の外軌側レールR1の頭部R11側面までの距離Lを測定するステップと、測定した距離Lと、外軌側レールR1の頭部R11側面に摩耗WEが生じていない場合の基準距離L0との差に基づき、曲線軌道の外軌側レールR1の頭部R11側面の摩耗WEを評価するステップと、を含む。【選択図】 図1
