Nonlinear compressuion connector
Nonlinear compressuion connector
(OP)
Please let me know what kind of options I have to purchase a nonlinear connector? Conical springs might be an option, however, I am more interested in a rod shape compression spring that has a variable rate.
Thanks

What are the forces, deflection and size required from the spring?

RE: Nonlinear compressuion connector
I am interested in a connector that behaves such as a hardening sping. As it deflects more, rates increases. In addition, there is geometrical limitations. Maximum OD is 0.5" and minimum ID is 0.2". Force is about 70-80 lb. Relaxed length is about 0.2 " .
So, there are couple of questions:
1) Generally, What kind of connectors can provide this behavior?
2) To design a nonlinear conical compression spring, how can I define the spring parameters? Does each coil have to fit into the next coil?
3) Is there any rod shape non-linear compression spring (equal ODs at both ends) available ? e.g. made of rubber, or polymer?
Thank you in advance

2. Physically you will not be able to get 70-80 lb from such a small spring made of coiled wire or strip.
3. A conical spring where each coil fit into the next coil will have a linear behavior.
4. You didn't give the spring deflection to get the 70-80 lb force.
5. When you say "relaxed length" do you mean the free length when the spring is not loaded?
I think you should check your design and see if you can free more space.
If you can give more information on the application it may help.

Why are you avoiding giving more information? This goes nowhere and there is not much point to continue this thread.
