L. Figures, ) montrent également que les 3 super-éléments restants donnent globalement les mêmes résultats, ce qui signifie que 40 pseudo-modes à fréquence maximale sont suffisants pour obtenir les meilleurs résultats possibles avec la méthode de Craig-Bampton dans le cas préchargé, tout comme dans le cas non préchargé. En revanche, les résultats de ces super-éléments s'écartent plus de la réponse de référence lorsque la précharge augmente : l'écart dépasse 1 dB à partir de 1300 Hz environ dans le cas non préchargé, contre 1080 Hz

. Dans-le-cas-présent, qualité des résultats" est celui à 180 pseudo-modes à fréquence nulle et 40 pseudo-modes à fréquence maximale. Les facteurs de fréquence de ses deux bases dynamiques sont proches de 0,4 et de 0,7. Ces facteurs restent en accord avec le cas non préchargé, ce qui semble indiquer que la méthode de Craig-bampton n'est pas perturbée par la précharge. Les temps de calcul de la méthode de Craig-bampton dans le cas amorti préchargé restent les mêmes que les temps de calcul du cas non préchargé (Tab. 3.6) Le facteur de gain de temps de calcul est de 50
