I am interested in the relative magnitudes of k and c values of automotive suspension during bounce and re-bounce.
The relative magnitudes of k and c values depend a lot on the geometry and the material of the limiting elements. Often made of rubber, the best way to get the k and c values is to model the bounce and re-bounce parts using FE codes and make numerical experiments. It turns out, that k and c depends a lot on the deformation and are non-linear functions - also depending on load frequency like Maxwell-elements. So, a non-linear material model has to be chosen in the analysis and some experiments an needed of get the material parameters.

Thanks for your answer Mr. Christian. I am interested in the relative difference of k and c between bounce and re-bounce. Right now, I am testing different values on a quarter car simulation using sinusoidal road inputs to see which has optimum road holding and ride comfort.
Mr Siddharth Ramakrishnan my suggestion try to simulate half car model with iso road profiles.
