Manufacturable Extension Spring
Manufacturable Extension Spring
(OP)
Hi,
I want to design a spring that is manufacturable.
I need to know acceptable values for number of active coils and initial tension for extension springs.
I am using 0.63mm dia spring steel.
I have got 8.5 active coils and an initial tension of 1.337N which is 8.5% of the max spring force.
Does anyone know how/where I can find out more info. on this subject.
Thanks

RE: Manufacturable Extension Spring
However, if spring designing is not your main work and you need to design a spring very rarely or/and your design is for critical use (fatigue, limited space, aerospace or military use etc.) I would recommend seeking the help of a proffesional.
RE: Manufacturable Extension Spring
I haven't got the books you mentioned- I should buy one of them.

You may want to visit the Extension Springs pages at www.efunda.com (Engineering Fundamentals). Many online calculators and resources came up with a simple Google search using the keywords spring design.
