Bolt Forces - What does axial load represent?

Hi all,

 

First post here so please be gental

 

I am looking at bolt loads with the "list pin/bolt/bearing forces" option in simulation. The bolts are showing both axial and bending forces.

 

I looked on the Swx website and it only states that the loads are at the bolt head which makes sense.

 

My questions is, are the axial forces evaluated at the neutral axis of the bolt? Or are they the maximum axial forces that the bolts are experiencing which would be a combination of the axial and bending loads.

 

Thanks in advance,

 

Dave

Correct Answer

Hi David, good question. My understanding is axial forces are the axial forces in the bolt. The bolt is just a simplified to a beam in the end so it is basically the same as the axial force in a beam. Bending force is a separate output.

 

Maybe to go deeper, what are you trying to do with the data, what are you trying to compare it to, what are you concerned with? My suggestion would be to setup a known condition and see what you get for comparison. Best way to test it.
