Hello community,
I need your support. Which solution is better?
How would you set the constraints and power? Is the solution approach using the creo assembly the right one?
Thank you for your support.

Hallo Community,
Ich brauche eure Unterstützung. Welche Lösung ist die bessere?
Wie würden Sie die Einschränkungen und die Kraft festlegen? Ist der Lösungsansatz über die creo Baugruppe der richtige?
Vielen Dank für Ihre Unterstützung.

Hello,
I have looked at your example. It looks fine to me.
I still have one question. You specified 20kN for the preload force of the bolts. In the bolt calculation graph,
the preload force starts at 16.75kN. How should this be interpreted?

With the preload force of the screw feature, the flexibility of the screwed parts is not known before the calculation.
The screw (spring) is therefore preloaded, causing the flanges to yield slightly, resulting in a slight loss of preload force.
The real preload force is therefore slightly lower than entered.
Bei der Vorspannkraft des Schrauben-Features ist die Nachgiebigkeit der verschraubten Teile vor der Berechnung nicht bekannt.
Die Schraube (Feder) wird also vorgespannt, dabei geben die Flansche etwas nach, dadurch geht die Vorspannkraft verloren.
Die echte Vorspannkraft ist somit etwas kleiner als eingegeben.
