Summary

Since damping has a major influence on the dynamic response of space launchers, virtual testing prediction becomes a major issue. A procedure, using the LATIN method was develop to compute damping in the joints with a specific tool which gives access to the calculations which were previously unaffordable. In the first part of this paper we show how we can improve this virtual testing procedure, by including reduced order modelling techniques within the LATIN method to create damping virtual charts. Then, in the second part of the paper we see how uncertainties can be taken into account in these virtual charts using the lack of knowledge theory with proper generalized decomposition. Some numerical examples are given to illustrate these techniques.
