| ** On the relevance of constraining in dynamic analyses ** |
| [[https://www.youtube.com/watch?v=0GEj69NANc8|back view]] [[https://www.youtube.com/watch?v=RihcJR0zvfM|side view]] relevance of (improper) constraints on the dynamic behaviour of a structure. |
| Design is reliable in actual operational conditions ([[https://en.wikipedia.org/wiki/Boeing_CH-47_Chinook|link]]). |
| Added constraints stiffen up the structure, thus increasing natural frequencies. |
| However, a 0 Hz rigid body mode natural frequency may rise to a finite value due to added positioning constraints; the associate natural mode may be excited in resonance by dynamic loads. |

| Contatto piede-bronzina: interferenza radiale 0.03 mm (corpi discretizzati in accoppiamento nominale senza gioco né interferenza) |
| |
| Contatto bronzina-spinotto: gioco radiale 0.05 mm (corpi discretizzati con tale gioco di accoppiamento). |
| |
| Carico sullo spinotto: 28.8kN, da distribuirsi su area diametrale 20,9x60 mm^2. |
