solid rivits

(OP)
In aircraft desing, do you usualy model the solid rivits?  how do you deal with the diferent tickneses of sheet metal.

RE: solid rivits

Hi,

No, we are inserting 3D dittos, exactly like in v4, made from surfaces (its same library...).

You are thinking at k factor for the sheet metal parts? For this, you have to look in standards...

RE: solid rivits

(OP)
Maybe is should clarify.

I'm doing paper to cad or an old ww1 airplane. I don't use Catia on daily basis (I use Keycreator), but I know enough to complete this project.

My question is this;
I have a few sheet metal parts that are joined with rivets. Those parts differ in thickness from part to part. So I was not sure how it is done in the industry, Is the rivet inserted into the assembly and do you have different rivet files for different sheet metal thickness? Obviously there is going to be a different distance between the mushroom and the head.....or is it done some other way....

Hope that explains it.
I'm a Mold designer, not an aircraft eng. :)

RE: solid rivits

An other suggestion is to use the ABF workbench where U have rivets

RE: solid rivits

We don't actually model rivets.  We generally depict them simply as a point and line to show location and orientation.  There are hundreds of thousands of rivets on an aircrafe, even a small one like a CitationJet, and there is no where near enough computing power available right now to model these.

RE: solid rivits

When using ABF workbench to create fasteners you will not get a solid part with a rivet, you will get a representation and a mockup as an application to the assembly. The benefit is a easy tool to position fasteners and that Delmia can read it so you can easy perform a manufacturing balance. If you don't use delmia you can output a text file that contain all information about the fasteners like type, size, position, vectors and so on.
