Helical Compression Spring Design
Helical Compression Spring Design
(OP)
Evening Folks,
I'm intentionally trying to get myself into deep water. I am looking at designing/specifying a helical compression spring, but being honest, I know next to nothing on the subject. I think we covered it at university many moons ago.
So, I would like some pointers, effectively an idiots guide you might say.
I know I should get one of my mechanical colleagues to do it, but we haven't got many at the moment and those we have are far too busy on more important stuff. So instead of leaving it on my desk for 6 months I thought I'd have a crack.
Any help would be much appreciated.

Israelkk, just to put your mind at rest, this spring I am looking at is a one time use and will only be used to push two steel plates together, no load cycles. Its of such minor importance the clever guys probably wouldn't even bother looking at it.
RE: Helical Compression Spring Design
Never underestimate the importance of any element in a system - consider the impact on the process / procedure / operation if the spring doesn't achieve it's purpose. Examine the design - if the spring is essential, then it's purpose is essential. "Never spoil the ship for a ha'pth of tar"!

I am attempting to detail a 'quick release connection' This steel frame will be deployed subsea and needs to be dismantled by an ROV. The spring idea was to go on a bolt with a large cotter pin to ensure the end plates stay in contact. Basically a large spring nut. The cotter pin can then be pulled out by the ROV and the connection dismantled. The connection should not be loaded at all and I am designing for the case of accidental impact.
Any alternative suggestions perhaps?
RE: Helical Compression Spring Design
Israelkk is right, however, about the complexity of doing a thorough job. Fatigue, relaxtion, temperature, and material properties are all part of the picture.

It's useful to engineers, too.

Absolutely the best reference I could dream of, better than Timoshenko, which is a statement in itself.
Good luck, but really, just passing on the fortune.
