Abstract

In this paper new research approaches based upon the opportunities of a new unique testing rig are presented. The Hexapod test rig at the TUHH enables researchers to excite large test specimens of for example aircraft cabin interiors under various transient and stationary periodic dynamic loads in all six degrees of freedom. The research projects treat the lack of dynamic parameters of material and structure behavior for better simulation based predictions in dimensioning of these lightweight products. Also the aspect of different product variants in dimensioning is targeted. As of great importance for such experimental parameter determination, the experimental design with the adoptions necessary in practice and their influence on the outcome are a research topic.

Keywords: lightweight design, dynamic load cases
