Please, if you could have a look on attached. This is sort of a assembly with desired proportions. I can not get 2D contact working on this one. Thanks a lot for your help.
... i get Error message saying: "Error in reading RSe stream" so it won't open them.
You are using 2011 while Hugh saved in 2013. Inventor files are not backward compatible.
I know you stated 2011 in your first post, but you should add this information to your signature.
Are you a student? (students can download 2013 for free from http://www.autodesk.com/edcommunity )
Yea, i will add it in there. I thought it might had been something like that. And no, i am not a student any more. I finished university last year. Now i am working for company in London.
The second simulation you posted up looks correct to me.
As you've shown, the maximum reaction force on the roll head in the rolling joint is computed by DS as ~96.035 kN.
Summing moments about the pivot point of the roll assembly (Revolution:2), and solving for the reaction force on the roll head comes out to be ~105 kN by my rough hand calculation. (I used the combined CoG of the roll head and roll assembly as the point of application of the centrfugal force)
I trust the Dynamic Simulation numbers more than my rough hand calculation...and this gives me confidence in both results, since they are somewhat close
Warm regards, -Hugh
[Edit: add photo of hand calc]
many thanks for your help. All this was about calculating force by which roll head acts on the ring. We are upsizeing existing device and we would like to know if the bearings are big enough. You helped me a lot.
