Title (EN) WORK MACHINE VIBRATION MONITORING METHOD AND SYSTEM
(FR) PROCÉDÉ ET SYSTÈME DE SURVEILLANCE DE VIBRATIONS DE MACHINE DE TRAVAIL
(JA) 作業機械の振動監視方法及びシステム
Abstract:
(EN) This vibration monitoring method has a step for displaying the number of times a tool passing frequency (TPF) peak that is the peak acceleration at a tool passing frequency has exceeded a TPF threshold value in a display column 56a of a total threshold crossing display part 56, a step for displaying the number of times harmonic TPF peaks at harmonic frequencies have exceeded harmonic TPF threshold values in display columns 56b–56d of the total threshold crossing display part 56, and a step for displaying a comparison of the number of TPF threshold crossings and the number of harmonic TPF threshold crossings in a variation display part 58.
(FR) L'invention concerne un procédé de surveillance de vibrations comprenant une étape consistant à afficher le nombre de fois où un pic de fréquence de passage d'outil (TPF), qui représente l'accélération de pic à une fréquence de passage d'outil, a dépassé une valeur de seuil de TPF dans une colonne d'affichage (56a) d'une partie d'affichage de croisement de seuil total (56), une étape consistant à afficher le nombre de fois où les pics de TPF d'harmoniques à des fréquences harmoniques ont dépassé des valeurs de seuil de TPF d'harmoniques dans des colonnes d'affichage (56b–56d) de la partie d'affichage de croisement de seuil total (56), et une étape consistant à afficher une comparaison du nombre de croisements de seuil de TPF et du nombre de croisements de seuil de TPF d'harmonique dans une partie d'affichage de variation (58).
(JA) 振動監視方法は、工具通過周波数でのピーク加速度であるTPFピークが、TPFしきい値を越えた回数を、しきい値越え積算表示部56の表示欄56aに表示させる工程と、高調波周波数での高調波TPFピークが、高調波TPFしきい値を越えた回数を、前記しきい値越え積算表示部56の表示欄56b~56dに表示させる工程と、TPFしきい値越え回数と高調波TPFしきい値越え回数とを比較して変化表示部58に表示させる工程と、を有する。
