Bolt Simulation

Question asked by Nilanga Gamage on Sep 11, 2012

Hi,

 

I have defined 4 Counterbore screws as shown below.

Each bolts have following definitions

Head Diameter: 8.179

Nominal Shrank Diamter 4.165

Meterial AISI 316 SS

Threads/inch 32

Bolt Strenght 25000 psi

Torque 6 N-m

Friction Factor 0.2

 

The load is a remote load of 375 lbf. When I run the analysis, it shows about 0.03 FOS of the bolts and it should be wrong. No components fail. Can anyone tell what's wrong here?
