Hi,

I'm trying to find out wether a bolt will loosen or not.

In a static study, you can have an idea of wether your bolt is going to loosen or not by looking at bolt forces. If the axial reaction force is greater than preload then there will be a good change that the bolt could loosen.

Is there a way to make such predicition when several load cycles are involved ? I mean that statically the bolt is fine (it won't loosen under only one load cycle), but maybe if it is subject to several load cycles (say 1 million) it could loosen. Is there any way to make such prediction in SolidWorks Simulation ?

Thanks,

Alex
