Bolt Pretension

Parthiban B

Hi everyone,

 

I need to perform a bolt pretension analysis, I know the bolt torque as 98 Nm and diameter as 14 mm. I am unsure about how much pretension force to apply. I am try to model as 1d beam

 

Please help me.

Hi Partihaban
This info can be found in mechanical handbooks!
Found this link that might be handy to use
Bolt Torque, Axial Clamp Force, Bolt Diameter Calculator (engineersedge.com)

With your numbers it looks like 35kN would be a good starting guess
