3. Modeling A

3.1. Characteristics of modeling

The lyre is divided into 2 substructures, meshed in an identical manner and therefore conformal.

3.2. Characteristics of the mesh

Lyre 1

Number of knots: 6936

Number of meshes and types: 1080 SEG2, 4250 QUAD4 and 6250 HEXA8

Lyre2

Number of meshes and types: 1080 SEG2 ,4250 QUAD4et 6250 HEXA8

3.3. Tested sizes and results

Non-regression values of the calculated natural frequencies are tested.
