Thread Load Distribution
Thread Load Distribution
(OP)
I am designing a stub acme connection, and in this case, I will be pushing its limits more than normal. I am looking for any information about load sharing between threads for 2g or 4g threads. I have read in some more basic books to use two threads with equally distributed loads, but from my experience this assumption is quite conservative. Other books that distribute the load over the entire thread length, which is fine so long as you don't come anywhere close to failure.
Thanks in advance for your input. I think this could be a very interesting and useful topic of research!

That was a good read. I may be able to show that this data can (at least somewhat) extrapolate from square and buttress threads to ACME and stub ACME connections. I am surprised that so much load is borne through only 2-4 threads.

I would still be interested if anybody else has information to throw in.

Yes post you're calculations it will be interesting.
RE: Thread Load Distribution
I have attached an image of the equation, and their sample calculation.
The "In" I assume is a natural logarithm. But I cannot validate their calculation using a natural logarithm. I started to do the derivation myself (phew...it is unbearably long), and I began (although not finished) a much different looking equation (although it may be the same in solution). Do you know what this "In" function is? OR can you validate their calculation?

maybe ask the authors ?

I have attempted to contact the authors, but they haven't got back to me.
