Rolling bearing: stress on outer ring is ok...but in the inner isn't!
Rolling bearing: stress on outer ring is ok...but in the inner isn't!
(OP)
Hi
after a lot of test, my analisys about a roller between a small pportion of inner and outer ring came to convergence.
But there's a problem.
As you can see in the image file, the stress distribution on the outer ring is correct, but in the inner ring i can't see any concentration near the border of the rolling (so, it' wrong!)
The contact parameters are the same for both:
-Hard Contact
-Friction less
-Slave surface:roller
-Master surface:inner/outer ring
Then there's a pressure on the outer ring, and the inner ring is encastred.

What's wrong? I really can't realized....

As a matter of fact i've just submitted a new analisys with a more equal size of elements, because i saw some small difference in inner/outer mesh and got to the same conclusion too....i'll hope it works, unfortunately each analisys take about 13 hour, so i can't say nothing at this time.

PS: i post new link....hope they works correctly :)
