Abstract
Ein Verfahren, das durch mindestens einen Prozessor implementiert wird, enthält das Empfangen eines akustischen Signals von einem Schallemissionssensor (112), der an einer zuvor festgelegten Stelle an einem Gehäuse (102) einer Rotationsmaschine (132), die in einem Übergangszustand arbeitet, angeordnet ist. Das Verfahren enthält des Weiteren das Anwenden einer Signalenveloppen-Extraktionstechnik auf das akustische Signal zum Generieren eines transformierten akustischen Signals. Das Verfahren enthält ausserdem das Generieren eines akustischen Signatursignals auf der Basis des transformierten akustischen Signals und das Bestimmen eines Rissdefekts an einer stationären Komponente der Rotationsmaschine (132) auf der Basis des akustischen Signatursignals.
