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.

Location: Analysis page > Safety module

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 HyperLife Weld Certification commands. After importing the dummy, you need to run this command file once to establish the required tree structure in HyperLife Weld Certification.
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.
