Wall thickness of a conical component

[OYS]

Hi,

I have a component that is effectively a conical tube, into which a solid cone seats.

The internal cone has a load on it which is trying to pull it through the narrow end of the outer conical tube.

The outer conical tube has a threaded insert to anchor it at the larger end.

I'm trying to calculate to wall thickness required in the outer component to resist the inner cone pulling through.

Both components are metallic, internal cone angle 8deg.

Thanks

Tim

Yes, that's a solvable problem. Probably the easiest way is using FEA, but I have solved for a similar system (termination of aramid strength members in a spike and cone) by hand, and got good correlation with the test data.

You'll probably need to use Lame's equations if you are using steel on steel.

Thanks for the nod towards Lame's equations.

What I'm looking at is a very similar fibre termination system, compression cone.

Trying to do some analysis of some legacy products.

Cheers
