Descrizione
Si applica un vincolo di pressione a una faccia.
Utilizzo
- Cliccare su
o scegliere Modello → Vincoli meccanici → Vincolo pressione dal menu principale. - Cliccare su Aggiungi riferimento e selezionare una faccia nella vista 3D.
- Specificare un carico di pressione in MPa nella finestra.
- Se necessario, spuntare la casella per invertire la direzione.
Pressure load applied to a cylinder
Note
- La distribuzione della pressione sulla faccia è sempre uniforme e sempre perpendicolare alla faccia.
