Dummy Panel

Use the Dummy Positioning / Joint dof panel to rotate the dummy assemblies or specify the position of the H-Point of a dummy assembly. The dummy database must be organized as a tree structure.

Incremental Subpanel

Use the Incremental subpanel to rotate an assembly about the coordinate system specified in the tree structure. In this panel, you have an option to rotate about the child or the parent system. The min stop and max stop angles for the x, y, z, axis associated with the joint are retrieved from the dummy database. When the minimum and maximum angles are reached, the assembly is not allowed to rotate any further.
Option Action
entity selector Select components or multibodies.
rotate: child / parents Select whether to rotate around the child or parent system when rotating the assembly.
increment Specify the amount by which to increment the angle between stops.
x / y / z rot To rotate the dummy to the min stop or max stop of the x-axis, y-axis, or z-axis, click the corresponding symbols, << or >>.
min stop The min stop angle for the x, y, z, axis associated with the joint is retrieved from the dummy database. When the minimum angle is reached, the assembly is not allowed to rotate any further.
current The current position.
max stop The max stop angle for the x, y, z, axis associated with the joint is retrieved from the dummy database. When the maximum angle is reached, the assembly is not allowed to rotate any further.

H-Point Subpanel

Use the H-Point subpanel to position the dummy to the H-Point or rotate the entire dummy about the H-Point. For positioning, you can specify either the coordinates or a node for the new H-Point. For rotating, specify the axis of rotation and the angle. In either case, picking any component in the dummy is sufficient.
Option Action
entity selector Select components or multibodies.
position: coordinate / point - node Specify the coordinate values or select the node at which you want the H-point located.
rotate selector Specify the plane or axis around which to rotate
increment Specify the amount to rotate.

Command Buttons

Note: Do not use the Rotate panel in the Tools panel to rotate the dummy. Doing so corrupts the tree structure and produces incorrect results when you reposition the dummy.
Button Action
position Position the dummy.
reject Reject the current selection.
rotate + / rotate - Rotate the component in the positive or negative direction.
return Exit the panel.

Comments

FTSS/Arup FE Dummies for Dyna3D
The Dyna3D keyword import translator detects the use of an FTSS/Arup dummy and builds the required tree structure automatically.
When the import process is complete, the dummy should be ready for positioning immediately.
PAM-CRASH 2G Dummies
Altair provides an external translator that converts a GENERIS tree file into HyperWorks commands. After importing the dummy, you need to run this command file once to establish the required tree structure in HyperWorks.
Other Dummy Models/Mechanical Systems
The Dummy Positioning panel works for any FE mechanical system (comprised of joints and local coordinate systems) as long as the appropriate tree structure exists. If the tree structure does not already exist in the system of interest, you can use the Systems panel to create the necessary references.
This function requires a template file.
