The Outer panel page is illustrated in Figure 8.6.3. The user may define Part, Material, Thickness, Property, Contact, etc.

GEOMETRY

Part

The user may select Part to define outer panel. By clicking Define geometry button, the program will pop up Blank generator dialog box. For a majority of the models, the meshes of the flange part could be refined for a more precise simulation of roller hemming. The whole outer panel will be divided into two parts: Outer and Flange. The user may simultaneously define them to the outer panel part, as illustrated in Figure 8.6.4.

Figure 8.6.4  Blank generator

Material

The program will automatically define a default #36 material for outer panel. The user may click the BLANKMAT button to enter into the Define material interface to modify or create a material.

Thickness

The user may define thickness for the outer panel. The default thickness is 1mm.

Property

Property contains the selection of element formulation, number of integration points in thickness direction and shear correction factor. Generally, in order to obtain a better simulation result, it is suggested to modify the property of Flange. The number of integration points in thickness direction is 7, and the element formulation is 16.

CONSTRAINT

The user may define the single point constraints. Click the SPCs button to pop up a dialog box illustrated in Figure 8.6.5.

Figure 8.6.5  SPCs

The pre-defined constraint types are listed below:

All (UVWuvw): Constrain all the degrees of freedom.

Hinged (UVW): Hinged constraint. Constrain translation of all directions.

GuideW (UV): Constrain translation along U and V direction.

GuideV (UW): Constrain translation along U and W direction.

GuideU (VW): Constrain translation along V and W direction.

PlaneVW (U): Constrain part motion on VW-Plane only.

PlaneWU (V): Constrain part motion on WU-Plane only.

PlaneUV (W): Constrain part motion on UV-Plane only.

SymUW (Vuw): Define part symmetry about UW-Plane.

SymVW (Uvw): Define part symmetry about VW-Plane.

User define: Allow the user to customize constraints.

Note: Generally, it is recommended to select All (UVWuvw) to constrain the nodes on the outer panel to avoid displacement of the outer panel during simulation process.

CONTACT

The user may define the type and parameters of contact between single surface and outer panel part.
