Die dynamischen Eigenschaften eines Crew-Bulk-Rest-Compartments sollen durch das Anbringen von diskreten Zusatzmassen an strategischen Stellen, mit dem Ziel eine akustischen Verbesserung im Innenraum zu erzielen, verändert werden. Für die Ermittlung idealer Positionen der Massen, wird eine rechnergestütze Optimierungsstrategie auf Basis der Finite Elemente Methode entwickelt und deren Einsatzmöglichkeiten evaluiert. Es wird gezeigt, dass eine signiVkante Pegelreduktion im tiefen Frequenzbereich, sowie die Reduktion der Gesamtmasse, durch geeignete ModellkonVgurationen möglich ist.In order to improve the acoustic properties of a crew-bulk-rest-compartment, the dynamics of the structure are modified by strategically placing discrete extra mas...
