HL-T: 2000 The Basics of HyperLife Weld Certification (DVS 1612)
This tutorial guides you through a step-by-step process that covers all the major functionalities of HL-WC. By working through the tutorial, you can quickly learn the tool and start using HL-WC to evaluate the welded connections in your FE models using standard weld evaluation methods.
Before you begin, copy the file(s) used in this tutorial to your
working directory.
- HL-2000\sidedoor_gp.hm
- HL-2000\sidedoor_gp.h3d
Import the Model and Results File
-
From the Home tools, Files tool group, click the Open Model tool.
The Open Model/Results Files dialog opens.
- Browse for and select HL-2000\sidedoor_gp.hm as the model file.
- Browse for and select HL-2000\sidedoor_gp.h3d as the result file.
-
Click Apply.
Identify Weld Lines
-
From the Screen tools, click the Mark Weld tool.
The Mark Weld dialog opens.
-
Click Detect.
HL-WC identifies the welds present in the model and highlights them in red.
Once detection is complete, a message stating the number of weld lines identified is displayed.
The weld line browser is updated.
Add a Weld Line Manually
-
From the Screen tools, click the Mark Weld tool.
The Mark Weld dialog opens.
-
Enter hlw_T2#IC2#Outer_Frame_left in the search text box and
press Enter.
-
Right-click on the weld line and select Isolate > Weld + Comp from the context menu.
The weld line and its attached components are isolated in the modeling window.
-
Rotate the model and zoom in closer to view the weld line
clearly.
-
In the Mark Weld dialog, right-click on
hlw_T2#IC2#Outer_Frame_left and select
Delete from the context menu.
The weld line is deleted from the model.
-
In the Mark Weld dialog, click .
A node path selection panel is displayed.
-
Select the starting and ending nodes of the weld path as shown in the image
below.
-
Click proceed.
The newly created weld line is displayed in the Mark Weld dialog.
The weld line is also added to the WeldLines folder in the HyperLife Model Browser.
- Right-click on any weld in the dialog and select Show All to return to the full model view.
Modify a Weld Line
-
In the Mark Weld dialog, right-click on the first weld line, hlw_T2#Frame_left1#Frame_left7,
and select Isolate > Weld + Comp.
This lets you visualize the weld line and the two connected components in the modeling window.
-
Right-click again on the same weld line and select Isolate > Weld + Systems.
The systems of the individual segments that make up the weld line are isolated.
- Again, right-click on hlw_T2#Frame_left1#Frame_left7 then select Rotate Y > All.
-
The direction of the weld line segments are rotated, but the change is not
immediately apparent. In order to see the rotation, right-click on the weld line
name once more and select Isolate > Weld + Systems.
- Right-click on any weld in the dialog and select Show All to return to the full model view.
Delete a Weld Line
- In the Mark Weld dialog, right-click on the weld line named hlw_L2#IC4#IC41.
-
Select Isolate > Weld + Comp.
The weld line and its attached components are isolated in the modeling window.
-
Right-click on the same weld line once more and click
Delete.
The weld line is deleted from the model.
- Right-click on any weld and select Show All to return to the full model view.
- Close the Mark Weld dialog.
Screen Welds
-
From the Screen tools, click the Inspect tool.
The Inspect Browser dialog opens.
- Select Subcase 1 (Cruise) from the Subcase drop-down menu.
-
Enter a threshold value of 100.
-
Click Inspect.
Once the screening is complete, a dialog will display the number of failed weld lines.
-
Click OK.
The legend on the right side of the modeling window colors failed weld lines in pink.
- Optional: Click in the dialog to plot the ratio of the von Mises stress value of an element and the threshold value you provided.
- Exit the Inspect Browser dialog.
Define a Weld Specification
-
From the Setup tools, click the
Specifications tool.
The Weld Specification dialog opens.
- Select DVS 1612 from the Regulation drop-down menu.
-
Click Apply.
Parameters are applied to all the weld line evaluation points.
- Click OK.
Review Evaluation Points
-
From the Setup tools, click the
Points tool.
The Evaluation Points dialog opens.
-
Select hlw_T2#Frame_left#Skin from the weld line list.
Note: The Evaluate checkbox should be activated. Any weld lines that are marked as critical in the screening process are automatically selected in the Evaluation Points dialog.
-
Review the classification parameters.
The classification parameters for each weld vary depending on the weld type and the weld regulation selected.
- Review other weld lines at your own discretion then exit the dialog.
Evaluate and View Results
-
From the Run tools, click the Run Analysis tool.
The Evaluate Welds dialog opens.
- Optional: Enter a name for the run.
- Select Loadcase Comparison for the evaluation method.
-
Ensure that all three load cases are selected.
-
Click Evaluate.
A summary of the run appears.
-
Click OK to close the dialog.
The Results Explorer opens and the model is contoured.
-
In the Results Explorer, select
Location_4 from the first drop-down menu and
Max_Utilization from the second drop-down menu, then
click .
-
Zoom in on the model to view areas of interest.
-
Add tags to elements.
-
Under the Tag field of the Results Explorer,
click .
A guide bar appears.
- Select elements to tag.
-
Click on the
guide bar.
The selected elements are tagged with IDs and utilization values.
-
Under the Tag field of the Results Explorer,
click .
