Launch of SICODYN international benchmark
SICODYN international benchmark 2009-2011: numerical and experimental analysis correlation in structural dynamics
To improve the predictibility of numerical simulations, measure the a posteriori variability in experimental and numerical results on a real industrial structure.
Two successive phases:
1. Assessing the robustness of a blind calculation (design purpose);
2. Using experimental measurements to improve the modelisation (expertise purpose);
Blind and updating simulations will be carried out by participants.
Experimental results will be delivered by EDF.
The experimental-numerical comparison and the statistical result analysis will be performed by EDF.
What structure ?
The structure that will be used as a demonstrator is a one stage horizontal pump issued from EDF thermal plants.

What types of dynamic characterisation ?
At least:
- Modal analysis of the non-rotating pump in free-free boundary conditions;
- Modal analysis of the non-rotating pump in laboratory or industrial conditions.
