To provide an inspection method of a railway vehicle which can improve inspection efficiency while assuring an inspection accuracy during a periodic inspection regarding a fatigue damage.SOLUTION: This inspection method is an inspection method of plural railway trucks each of which have truck frames. The plural trucks have the same dimensional shapes and are used on the same tracks. The inspection method has a set process (#10), a use process (#20) and an inspection process (#30). In the set process (#10), plural railway trucks are allocated to either a first truck or a second truck. The truck frame of the first truck is a first truck frame which is relatively weak in fatigue strength and the truck frame of the second truck is a second truck frame which is relatively weak in a fatigue strength. In the inspection step (#30), the first truck and the second truck both used on the track are periodically inspected. In the inspection step (#30), a whole area of the first truck frame is subjected to a nondestructive test and about the second truck frame, important inspection points in the design aspect are subjected to nondestructive tests.SELECTED DRAWING: Figure 1

    【課題】疲労損傷に関して、定期点検時に、検査精度を確保しつつ、検査効率を向上できる鉄道台車の点検方法を提供する。【解決手段】点検方法は、各々が台車枠を備える複数の鉄道台車の点検方法である。複数の台車は、同一の寸法形状を有し且つ同一の路線で使用される。当該点検方法は、設定工程(#10)と、使用工程(#20)と、検査工程(#30)と、を備える。設定工程(#10)では、複数の鉄道台車を第1台車及び第2台車のいずれかに割り付ける。第1台車が備える台車枠は、相対的に疲労強度に劣る第1台車枠であり、第2台車が備える台車枠は、相対的に疲労強度に優れる第2台車枠である。検査工程(#30)では、路線で使用された第1台車及び第2台車を定期点検する。検査工程(#30)では、第1台車枠の全面を非破壊検査し、第2台車枠について設計上の重要点検箇所を非破壊検査する。【選択図】図1
