Fasteners In Mechanica

[Ryan]

I am using Pro/E WF 2.0 M220 and am having some trouble with fasteners in mechanica. How do you connect three pieces with a fastener connection?


You can see the red, green and gold pieces are three beams that will be riveted together. When I try to place a fastener with one end on the red piece and the other end on the gold piece, it gives me an error.<?:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" />


Next, I tried two fasteners, one going from the red piece to the green piece and the other going from the green piece to the gold piece, with the two fasteners overlapping through the green piece. That gave me an error as well.


I have interfaces on all of the surfaces, since I do not want them to mesh together. I only want the connection to be where the rivets will go through.


Any help would be appreciated.

Maybe I can ask a simpler question to start. Can a single fastener connection be used to attach through three pieces? (i.e. through the red, green and gold pieces above)

Dear Ryan,


Its possible by two ways. Go through the attachment. For second option, you have to give diameter value equal to the hole of intermediate i.e 2nd component. Let me know if you have any other doubt.

thanks for those links .... they are really useful

Thanks for the responses!


Vsingh: Before I posted, I tried both of the methods that you suggested. I did not have gaps between the parts though. I will have to run it again with some gaps. Were you able to get your models to mesh properly? I am specifically interested in Option 2.


muadib3d: Thanks for the links. There is some very helpful information from elite-consulting on their site.

If you want to run analysis then you have to keep gaps between parts.


Option 2 should work without gap. I can't check it now. But I think its possible. I will check it on monday (12th March). Please check what diameter you are entering in mechanica. It should equal or less then the hole dia. Also, you have to pick hole edges in proper sequence.

I could not get option 2 to run without a gap. Option 1 worked great for me! Thanks for your help, vsingh!

Ryan, for option 2: If you want to run analysis then you have to keep gaps between parts otherwise it will not mesh (because no meaning of bolt ifparts are in contact). If you dont want to mesh+run analysisthen its possible.Please go through the link.
