Compression spring design - Force, Rate and Deflection

Basic introduction to spring design. How to work out compression or extension spring rate, force and deflection. Spring free length, minimum working length, maximum working length & solid length. Spring stiffness. Spring calculation, spring load.

Thank you so mush

[@rameshhariharan2623]

this is great best easy to understand

Thanks! Glad to help!

NICE VERY HELPFUL

[@timeless8757]

Installation length will be 20% of ..... ?? Either free length or something any ??

[@PDWCreative]

Your working lengths and required force are whatever your design requirement is. You just need to bear in mind the free and solid / shut lengths needs considering as well

Nice

[@devilsdouble6935]

Good one.Thanks

F1 = 2.91N , Deflection-1 = 6.56mm ( 2 formulas where conflict). F1 = G x d4 x df1 / 8xD3 x Na , df1 = 8 x F x D3 x Na / d4 x G

Whether the pitch of spring doesn't have any effect on load

[@PDWCreative]

If you change the pitch the free length will change. If the loaded length stays the same this will have some effect on stress and force.

Height H, Mass M, spring compression x If Height 2H, mass M, What will be the compression

[@PDWCreative]

The compressed length should be at least one of your working lengths. Your spring design revolves around the required force and compressed loaded length. Once you know this you can start working out your spring free length, diameter, coil count and so on.
