DEGRADATION DETECTION SYSTEM, DEGRADATION DETECTION METHOD, AND DEGRADATION DETECTION DEVICE
To provide a degradation detection system which can more properly detect a degradation degree of a track on which a vehicle travels.SOLUTION: A degradation detection system comprises: a travel position acquisition part that acquires a travel position of a vehicle; an axle load acquisition part that acquires a downward weight in a vertical direction in a wheel shaft shouldering the traveling of the vehicle; an impact force input condition acquisition part that acquires information about a condition of an impact force onto a track when wheels of the vehicle pass the track; a stress calculation condition acquisition part that acquires information about a stress calculation condition to calculate stresses generated when the wheels of the vehicle pass the track; and a track degradation advancement calculation part. The track degradation advancement calculation part, in response to position information acquired by the travel position acquisition part, calculates and outputs the deterioration progress degree which indicates the deterioration progress degree of the track, using weight information acquired by the axle load acquisition part, information acquired by the impact load input condition acquisition part and information acquired by the stress calculation condition acquisition part.SELECTED DRAWING: Figure 2
【課題】車両が走行する軌道の劣化度をより的確に検知可能な、劣化検知システムを提供することを目的とする。【解決手段】前記車両の走行位置を取得する走行位置取得部と、前記車両の走行を担う車輪軸において、鉛直方向下向きにかかる重量を取得する軸重取得部と、前記車両の車輪が前記軌道を通過する際の前記軌道への衝撃力の条件に関する情報を取得する衝撃力入力条件取得部と、前記車両の車輪が前記軌道を通過する際に発生する応力を計算するための応力計算条件に関する情報を取得する応力計算条件取得部と、軌道劣化進行度算出部とを備え、軌道劣化進行度算出部は、前記走行位置取得部で取得された位置情報に対応させて、前記軸重取得部で取得された重量情報と、前記衝撃力入力条件取得部で取得された情報と、前記応力計算条件取得部で取得された情報とを用いて、前記軌道の劣化の進行度を示す劣化進行度を算出して出力する。【選択図】図２
