Connection conditions (Ansys workbench)
Connection conditions (Ansys workbench)
(OP)
Hi, Long time reader, first time poster.
CAD: NX6 & Solidworks 2010
FEA: Ansys Workbench 12
I'm struggling to decide on a course of action regarding the application of connection conditions. I have a 4 part assembly which is shown in the attached picture, in essence i have a double ended female taper sleeve, with connecting male tapers at each end, all held together with a screw. Currently I have negated the screw and have simply applied 'no separation' connections at the the taper interfaces.
The model will be subjected held at one end and a force applied at the other, in effect beam deflection. I would be interested to know if anyone can think of a better way the connect the parts.

RE: Connection conditions (Ansys workbench)
Overall, the methodology looks fine - good to see that you're taking advantage of symmetry; I assume that the loading is symmetric as well.
The only other things that I might consider would be to remove the exterior fillets and to remove the hex from the bolt to reduce the problem size a bit. You may consider modeling the mating part at the clevis connection if you're especially concerned with the stress in that location.
Consider your loading, whether it is static or cyclic. If you're dealing with cyclic loading, fatigue is likely a concern. In static loading, stresses in interior fillets generally yield out in steels. In cyclic loading, stresses in interior fillets develop into cracks and break your part.
