Mesh

\(\mathrm{E3}\)

\(\mathrm{E4}\)

:

\(\mathrm{N17}-\mathrm{N18}\)

\(\mathrm{E19}\)

:

\(\mathrm{N17}-\mathrm{N16}\)

Masses of corners

:

\(4.444\mathrm{kg}\)

Intermediate masses

:

\(0.783\mathrm{kg}\)

4.2. Characteristics of the mesh#

Number of knots: 28

Number of meshes and types: 52 (28 MECA_POU_D_T and 24 MECA_DIS_T_N)

4.3. notes#

The modes are normalized to the mass generalized to 1.

The overall response is obtained by quadratic combination of the modes, then successively a quadratic combination and a Newmark combination of the directions of the excitations.

4.4. Tested values: frequencies#

4.5. Values tested with quadratic combination of the directions of the excitations#

  • The movements of corners \((\mathrm{N9},\mathrm{N12},\mathrm{N17},\mathrm{N20})\) are the same,

  • The reactions to the \((\mathrm{N25},\mathrm{N26},\mathrm{N27},\mathrm{N28})\) supporters are the same,

  • Generalized efforts are expressed in the global benchmark.
