Descriere

Constrângerea greutății proprii este definită de către accelerația gravitațională de 9,81 m / s ^ 2 care acționează asupra întregului model în direcția prescrisă.

Cum se folosește

1. Click pe sau alegeți Model → Mechanical Constraints → Constraint self weight din meniul de sus sau apăsați tastele C apoi W.
2. Puteți modifica direcția gravitației schimbând coordonatele sale vectoriale în bara de proprietăți a obiectului nou creat ConstraintSelfWeight.

Script

• obiect nou

import ObjectsFem
ObjectsFem.makeConstraintSelfWeight( name )

• adăugați obiectul la analiza numită Analysis

App.ActiveDocument.Analysis.Member = App.ActiveDocument.Analysis.Member + [ (object) ]

• examplu:

import ObjectsFem
selfweight_obj = ObjectsFem.makeConstraintSelfWeight( 'MySelfWeightObject' )
App.ActiveDocument.Analysis.Member = App.ActiveDocument.Analysis.Member + [selfweight_obj]

Solver CalculiX

Limite

• Trebuie să modificați fișierul .inp pentru a edita accelerația gravitațională.
• Gerutatea proprie este aplicată elemetului set Eall înseamnă întreg modelul .

Editing CalculiX input file

Accelerarea constantă poate fi modificată prin modificarea manuală după generarea fișierului de intrare CalculiX.

Example of lines in .inp file:

*DLOAD
Eall,GRAV,9810,0.0,0.0,-1.0

where 9810 is gravity acceleration in [mm/s^2]
