Simplified, I have an assembly of a wheel hub with two tapered roller bearing cones assembled internally and that sitting on a plate. I have run a static analysis with the plate fixed and applying bearing loads on the cones (perpendicular to the hub axis). The results look as expected. Then I took the assembly, replaced the hub with a slightly different one and am trying to rerun the analysis HOWEVER, results look like the cones are not being bonded (the default interface setting) to the hub. Results show the cone deforming right thru the hub and the hub stress almost nonexistent. I do not see any failures in the assembly and I have walked thru all my contraints and loads to verify nothing has been "lost" in the hub replacement. Oddly, the bonded joint between the hub and the plate appears to be functioning just fine. Anyone have any idea what's gone wrong? What would the replace have done? And more importantly, how do I fix this?
Attached is a picture of the two runs where you can see the cone coming thru the hub on the "replaced run", but sticking with the hub on the "first run" just as it should...
thanks in advance...
