3. Modeling A

3.1. Characteristics of modeling

An expansion of the measurement is carried out using an expansion base composed of static readings at the measurement points.

We use 3D modeling for the tube and DIS_T modeling for the supports.

3.2. Characteristics of the mesh

The mesh contains 8680 elements of type HEXA8 and 20 elements of type POI1.

3.3. Tested sizes and results

We test the non-regression, for the first four modes of the tube, of the dot product between the extended modal deformation field and the modal deformation field calculated with the initial numerical model.

The results obtained are considered correct here despite the fact that the expansion base is composed only of static surveys.
