Lebenszykluskosten beeinflussen das Potenzial
kontinuierlicher Strukturüberwachung
Eine kontinuierliche Zustandsüberwachung erhöht die Kenntnis über nutzungsabhängige Strukturschäden und beeinflusst die Restlebensdauer.
Dieses Potenzial kann auch dazu genutzt werden, Strukturen a priori leichter auszulegen.
Life-cycle costs affect the potential of continuous structural health monitoring
Continuous condition monitoring increases the knowledge of usage-dependent structural damages and influences the remaining service life.
This potential can also be used to design structures a priori in a lighter way.

Aktive Strukturüberwachung
ermöglicht genauere Last- und

SHM kann abhängig vom optimalen ökonomischen
Zeitpunkt der Außerdienststellung und der erfahrenen
Betriebslasten sowohl die Strukturlebensdauer
verlängern als auch Gewichtseinsparungen während
der Auslegung ermöglichen.
Active structural health
monitoring enables more precise
load and damage tracking
Depending on the optimum economic timing of
decommissioning and experienced operating loads,
SHM can both extend structural life and provide
weight savings during design.
