Hello, hello, hello,
Typical springs are designed as linear force/displacement devices, thus :
Force = +- SpringConstant * Displacement.
The SpringConstant, as the name suggests, is a constant and displacement-independent.
Can the SpringConstant be calculated/simulated from the spring geometry and its material properties?
For typical mortals, it would be very hard to do it reliably. Many analytical formulas have been developed for typical geometries. The numerical FEA is an option; however, the nature of the internal matrix representation is prone to accumulating rounding errors, which can affect the solution. The real material properties are also the big unknown.
Nevertheless, there is a pragmatic solution (in most scenarios) that requires some sort of scale and a calliper-like device (or professional spring dynamometer). A piece of paper and a pencil would also be handy. The gathered data table (or the single scalar) can be used in the F360 spring model using the userParameter approach.
Some time ago, I presented such a simple model. Consider checking:
