Bolt preload definition
Bolt preload definition
(OP)
Good day team,
I would like to know if you can give me an explanation about how to define bolt preload.
I asked some peers about it, and they told me that my preload needs to be the same as the acting force, is this necessary true? because in some point the tension force in the bolt will duplicate.
I research about it and found that it helps the joint to withstand more load, but I did not find anything about how to establish the required preload.
The application will be for a 2 bolted V-clamp.
If you can please provide me any sources in which I can research more, that would be great.
Thanks in advance!

The 2nd reason for preload is to reduce fatigue effects when you have varying tension loads.

If so, I think the wedging action and friction and clamp distortion would make figuring the required bolt clamping and thus preload kind of complicated.
