PC RAILROAD-TIE DETERIORATION DETERMINATION SYSTEM, PC RAILROAD-TIE DETERIORATION DETERMINATION METHOD AND PROGRAM
PROBLEM TO BE SOLVED: To provide a PC railroad-tie deterioration determination system capable of grasping a deterioration state more easily.SOLUTION: The PC railroad-tie deterioration determination system comprises: a vibration measurement part 200 for measuring vibration of a PC railroad-tie which is excited; a characteristic frequency detection part 191 for detecting a characteristic frequency in a bending third mode based on the measurement result of the vibration; and a deterioration determination part 192 for determining that the PC railroad-tie is deteriorated when it is determined that the characteristic frequency of the bending third mode detected by the characteristic frequency detection part is lower than a predetermined condition.
【課題】劣化状況をより容易に把握できるＰＣまくらぎ劣化判定システムを提供する。【解決手段】ＰＣまくらぎ劣化判定システムは、加振されたＰＣまくらぎの振動を測定する振動測定部２００と、振動の測定結果からたわみ３次モードの固有振動数を検出する固有振動数検出部１９１と、前記固有振動数検出部が検出した前記たわみ３次モードの固有振動数が所定条件よりも低周波であると判定すると、前記ＰＣまくらぎが劣化していると判定する劣化判定部１９２と、を具備する。【選択図】図１
