Subject: Substructuring-Contact analysis
Author: Amar Atre
Date: 2003-02-17 09:41:00

Hello
I am doing a 2D contact analysis of a rack driving a gear which is
constrained to rotate on a hub. There is a clearance of 1 micron
between the gear and hub.The hub is fixed. Displacement is applied to
the rack. There is no constraint on the gear. So contact is between
the gear teeth and rack and gear and hub.this is with PLANE 42 .
Educational version.
I am trying this by substructuring. I made the gear a superelement
with MDOFs where contact occurs. Now in the Use pass ( the manual isnt
quite clear on this) i create the rack and hub ( non-superele). To
create the contact elements do i create the gear again and create
contact elements and then read in the superelement file? or do i read
in the superelement file and create the contact elements at the MDOfs?
I am not exactly clear as to how to create the non-superele contact
elements? also is substructuring really useful? the manual gives just
one example on it.
Please advise.
