NonLinear Springs
NonLinear Springs
(OP)
Would be glad if someone can provide me information (or URLs) of places where I can buy nonlinear compression springs. It can be those 'not consistent' wound springs or even rubber tubings ... Many Thanks

Also what about fatigue properties of rubber. can I model these theoretically?

Brakeman, if you look over a car you will find many non linear rubber springs. Assuming you want an axial compression spring then you can use snubbers, which are typically truncated pyramids or cones of rubber that gradually come into contact with a metal part, or you can use things like jounce bumpers, which are long polyurethane foam cylinders that you see on the shaft of a shock absorber. http://www.shockwarehouse.com/cgi-bin/shocks/misc
Alternatively use rubber in shear, like an engine mount.
