Aligning a component normal to another component

Terence_20729

I am currently trying to run an OptiStruct Explicit simulation between an impactor and a door. I want to move the impactor at different locations and study the resulting stress and displacement. Since the door is curved, I want to ensure that the impactor and door are aligned in the normal direction during impact.

 

In HyperWorks, how do I move/align the normal directions of two components?

I would probably recommend the position tool.

Changing position is accomplished by picking six nodes that define a transformation for the selected entities. Three nodes represent the entities' starting position, and three corresponding nodes define the selected entities' ending position. The transformation (consisting of translations and rotations) that maps the differences between the two sets of nodes is applied to the selected entities until they are relocated.

Entities are positioned in space by first translating N1 of the first group of nodes to N1 of the second group. Next, the entities are rotated around N1 until the two selected N2 nodes are aligned along the same vector (using N1 as the vector's origin). Finally, the entities are rotated around the (N1, N2) axis until the two N3 nodes are in the same plane.
