Bolt Connectors through slots

1-L5M1MV Aug 29, 2009 10:41 AM

Hopefully someone can shed some light on this subject -- I'm running non-linear dynamic analyses on some sheet metal parts with slotted bolt holes, and I need to analyze the bolt stresses on the part. I've tried adding washers to the assembly, then using the circular edges of the washers for the bolt and nut faces, but it really slows down my study. Slotted bolt holes aren't uncommon so I assume that SolidWorks has the ability to simulate a bolt, but I'm not sure how. Thanks,

Alternatively, can I convert bolts from an assembly to bolt connections in a simulation? If so, I can constrain the bolt to the middle of the slot in the assembly and apply a bolt preload during the simulation pre-processing. Along with appropriate friction and no penetration constraints, I would think that method may accurately represent a bolted slotted connection.

  I have a similar issue except my bolts are contacted in the center so I can't use sim bolts. So I created test rods with nobs on the end and left the knobs bonded to the slots. To make sure it won't slide in my next test I am going to bond washers and run sim bolts with tension on them. I have no idea if this is going to work or not but it what I would try.
