PROBLEM TO BE SOLVED: To provide a device to numerically identify a contact position between a wheel of a traveling railway vehicle and a rail that can identify even in a railway vehicle to which usual wheel shafts are installed, not using a special and expensive PQ wheel shaft, a contact position between a rotating wheel and a rail easily and automatically by performing numeric conversion of the contact position, and to provide a method of numerically identifying a contact position between a wheel and a rail.SOLUTION: A device for numerically identifying a contact position between a wheel of a traveling railway vehicle and a rail includes an infrared thermography camera 7 attached to a carriage component of the railway vehicle and capable of detecting radiating heat. On the occasion of attaching the infrared thermography camera 7 thereto, there is used a fixture 8 for the infrared thermography camera 7 having a vibration-proofing function that prevents malfunction of the infrared thermography camera and shaking in photographing even under an excessive vibration acceleration environment of a traveling railway vehicle.SELECTED DRAWING: Figure 1

    【課題】 特別で高価なPQ輪軸を使用せずに、通常の輪軸を装架する鉄道車両でも、容易にかつ自動的に走行中の車輪とレール間の接触位置を数値化して特定することができる、走行中の鉄道車両の車輪とレール間の接触位置を数値的に特定する装置及び車輪とレール間の接触位置を数値的に特定する方法を提供する。【解決手段】 走行中の鉄道車両の車輪とレール間の接触位置を数値的に特定する装置において、放射熱を検知できる赤外線サーモグラフィカメラ7を鉄道車両の台車部品に取り付け、その取り付けにあたり鉄道車両の走行中の過大な振動加速度環境下でも前記赤外線サーモグラフィカメラの故障や撮影ブレを生じさせない、防振機能を有する前記赤外線サーモグラフィカメラ7の取付治具8を具備する。【選択図】 図1
