3. Modeling A

3.1. Characteristics of modeling

The lyre is divided into 3 substructures, meshed in an identical manner and therefore conformal.

3.2. Characteristics of the mesh

Lyre 1

Number of knots: 10560

Number of meshes and types: 1196 SEG2, 5522 QUAD4 and 9735 HEXA8

Lyre2

Number of knots: 10560

Number of meshes and types: 1196 SEG2, 5522 QUAD4 and 9735 HEXA8

Lyre3

Number of knots: 17072

Number of meshes and types: 1952 SEG2, 8778 QUAD4 and 15840 HEXA8

3.3. Tested sizes and results

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