The Tube setup page is illustrated in Figure 8.5.6. The user may define Part, Material, Thickness, Property and contact.
Figure 8.5.6 Define tube
Geometry
Part
If the tube mesh has been created in the new setup, it will be automatically defined to the tube part. Otherwise, click Define geometry button to display a dialog box illustrated in Figure 8.5.7.
Figure 8.5.7 Define geometry
Add part: select a part from the Part list to define tube
Remove part: remove the selected part from the Part list
Copy element: copy a new element from the existing one.
User define: user define the tube
Display: only display all the current parts that defined in the Part list
Exit: exit the Define geometry dialog box
The user may also define the tube mesh according to requirements. Click User define button to display the Define Geometry dialog box illustrated Figure 8.5.8.
Figure 8.5.8 Define geometry
Outer Diameter: outer diameter of tube
Full length: full length of tube
Initial feed: initial feed of tube
Element size: the amount of the mesh segments along tube axis direction
Location: define the location of starting point for tube bending and the point is also at the tube axis
Direction: define the tube axis direction
Reverse: define the reverse direction as the bending direction after the generation of mesh
Flip: define the reverse direction as the bending direction before the generation of mesh
Apply: after clicking this button, the program will generate mesh according to the parameters
Undo: cancel the operations for mesh generation
Close: exit the current dialog box
Material
The program will automatically define a default #36 material for each tube part. The user may click the BLANKMAT button to enter into the Material definition interface to modify or create a material.
Thickness
If the user has created the
tube mesh, the default tube thickness is the thickness defined during the
creation of tube mesh. Otherwise, the default thickness is
Property
Property contains the selection of element formulation, number of integration points in tube thickness direction and shear correction factor. Generally, the user does not need to modify Property.
CONTACT
The user may define the contact types and contact parameters of single surface, and between tube parts.
