Hanging mass in Motion Analysis

Question asked by David Beltran on May 9, 2012

Hello,

 

I am trying to model a mass hanging from a pin that goes through 4 plates.  I'm looking for the stress on the plates due to the hanging mass.  When I modeled it, only one plate shows to be loaded (see image 1 & 2).  The plates are fixed, pendulum has concentric mate to one of the plates.  PlateGroup_01.jpgPlateGroup_02.jpg

 

I then added concentric mates to rest of the plates and the results now show 2 plates being loaded (see image 3), why not all four?

How do I get all 4 plates to see load without adding redundant constraints? Do I use contact? 

 

Thanks.
