The ABAQUS model of standardized steel box girder is established, and the plug-in of RSG is used for secondary development

The problem to be solved in this example is to use the length of the upper flange SB And steel box girder height H Parametric modeling of steel box girder

Then add the command flow and GUI Graphical interface combination , Make a small plug-in , To facilitate the next use .

First ,abaqus Medium python Modeling command flow statements are too complex ,
So we get the complete code command through actual modeling

At present, there are two ways ：
1. It's using python reader Direct reading display （ There was an introduction before , Readers can go to the previous blog to download ）

2. Is recorded through macros , It opens at file Medium Macro Manager To record , After the abort, it will draw a in the directory py file .

With the basic code  

We just need to define a function and variable ,
Again python of use def function(x,y) : Defined function

x,y Is the change we want to set , Here it refers to length and width

from abaqus import *
from abaqusConstants import *
import math


def createPlateFunction(SB1, SB2, H):
    s = mdb.models['Model-1'].ConstrainedSketch(name='__profile__',
                                                sheetSize=10000.0)
    g, v, d, c = s.geometry, s.vertices, s.dimensions, s.constraints
    s.setPrimaryObject(option=STANDALONE)
    s.rectangle(point1=(0.0, 0.0), point2=(SB2, H))

    s.Line(point1=(0.0, H), point2=(-SB1, H))
    s.HorizontalConstraint(entity=g[6], addUndoState=False)
    s.PerpendicularConstraint(entity1=g[2], entity2=g[6], addUndoState=False)
    s.Line(point1=(-SB1, H), point2=(-SB1, (H - 500)))
    s.VerticalConstraint(entity=g[7], addUndoState=False)
    s.PerpendicularConstraint(entity1=g[6], entity2=g[7], addUndoState=False)
    s.Line(point1=(-SB1, (H - 500)), point2=(0.0, (H - 750)))
    p = mdb.models['Model-1'].Part(name='Part-1', dimensionality=THREE_D,
                                   type=DEFORMABLE_BODY)
    p = mdb.models['Model-1'].parts['Part-1']
    p.BaseShellExtrude(sketch=s, depth=5000.0)
    s.unsetPrimaryObject()
    p = mdb.models['Model-1'].parts['Part-1']
    session.viewports['Viewport: 1'].setValues(displayedObject=p)
    del mdb.models['Model-1'].sketches['__profile__']

With the function code, we set out to build a graphical interface

Select in menu plug-ins After coming down, choose abaqus Medium RSG dialog
plug It means plug , The plug-in generated later will also appear here .

open RSG And then this interface appears

We choose the menu bar on the left to combine ,

Pay attention to the settings here keywrod Consistent with the variables you set

This is a simple interface
And then in kernel Import the saved py file , It's the function file that appears above

Click on OK Save the path , Will generate 6 File , This is our plug-in file

Then close abaqus Rerun , Will be in plug-ins Found a newly written plug-in in gxl1

We can quickly model the side span of steel box girder , And then combine it , Greatly reduce modeling time .
