The info in this thread is great!
I have a collection of resources now, I've saved some links from here and I'll bookmark this thread as well.
I've also set up a simple Excel file for myself which allows me to enter the bolt properties, suggested tightening torque values (VDI2230), joint...
Yeah, I know the load will get spread between a number of bolts. Just focusing on one bolt now to understand the theory.
I did a few calculations and actually in my case the "plate" is really thick and bolts are skinny, so the joint constant is only C = 0.07 (I found this online tool for quick...
Thanks goutam_freelance and desertfox for those formulas for calculating FOS against joint separation. You've both described the same thing and both of those methods will give the same results.
So, in the example of that bolt with 40 kN pretension and 30 kN external load applied to it...
No, I think I got that right. It seems that when external load P is applied, part of it (C * P) goes into relieving clamp force and the rest ((1 - C) * P) will go into increasing the tension in the bolt. This slide from desertfox's link seems to illustrate is as well:
See how the bolt...
Thanks for the great response everyone!
Yeah, I can clearly see where my original logical error was. The theory of how it actually works (which is really clearly explained in the link in desertfox’s original response) does seem counterintuitive at first glance but makes perfect sense when I...
Hi all,
I hope its not a stupid question, or if it is then maybe someone can point towards that "simple and obvious" answer that I'm failing to see here! Here goes:
I haven't got much experience with bolted joints, so far simple guidelines such as VDI2230 have helped me out just fine...
