These resonances correspond to parasitic resonances of the APA itself.
They are very close to what was estimated using the FEM:
- X-bending mode at ~190Hz (Figure [[fig:mode_bending_x_bis]])
- Y-bending mode at ~290Hz (Figure [[fig:mode_bending_y_bis]])
- Z-torsion mode at ~400Hz (Figure [[fig:mode_torsion_z_bis]])
- X-bending mode at around 190Hz (Figure [[fig:mode_bending_x_bis]])
- Y-bending mode at around 290Hz (Figure [[fig:mode_bending_y_bis]])
- Z-torsion mode at around 400Hz (Figure [[fig:mode_torsion_z_bis]])

#+begin_important
Depending on how the APA are mounted with the flexible joints, the dynamics can change a lot as shown in Figure [[fig:struts_frf_dvf_plant_tf]].
In the future, a "pin" will be used to better align the APA with the flexible joints.
We can expect the amplitude of the spurious resonances to decrease.
