compression spring design proof
compression spring design proof
(OP)
We are currently working on establishing proof for the design of a number of compression springs. We've done the lab testing to get output results but management is also looking for analytical data to support the findings (does the engineering match the product kinda stuff). Ergo - I'm looking for a good compression spring calculator to help proof this (and save me from many hand calcs). Knowns are wire dia and matl, all dimensions, and a load at working height.
thanks
thanks

This is a good prog :

Also you can do a FEM analysis if you have the spring dims and material.

My machine design textbook from collge has a whole section on spring design. This ought to be a feature of all machine design books, right?
Design of Machine Elements -- Fourth Edition
Virgil M. Faires
MacMillan
Second hand copies of this are available all over the place.
There is a Spring Design Manual published by SAE. The Belleville spring equations are not quite identical to the ones in Roark's 5th Edition. I have not looked at their helical spring calculations.
If you set all this stuff up in a spreadsheet, you can punch in the charactersistics of springs from catalogues like Associated Spring SPEC. The numbers should work.
