Abstract
The dimensioning of lightweight structures under stationary dynamic loading is a challenging task, especially in highly variant product structures. A methodical approach using dynamic substructuring algorithms was developed to support simulation based vibration behaviour prediction of a modular product structure and improve the dimensioning for highly variant lightweight structures. The contribution focuses on the methodical model preparation with consistent interface and system boundary definition. The approach is explained using an example from the aircraft cabin.
