Hello, I want to simulate the contact of a mass-spring-damping system with a material, to evaluate the mechanical behaviou and the rebound amplitude. I have done this using the "Traslational Hard-Stop" block where the material response is simulated as an elastic component and a damping component (k*x+sigma*vx).
Is there a way to change the equation of the block to complicate the response of the material with a model that consider more springs and dampers in series/parallel? I mean, is there a way to change the form of the reaction force directly through the block?
If not, is there a way to replicate the behaviour of the block, but with a different reaction force?
Thank you in advance!

Hi Raffaele, If you are interested in a more complex material response involving multiple springs and dampers, I think you might need to consider creating custom Simulink blocks and equations. As far as I know, it's not possible to directly modify the equation within the existing "Traslational Hard-Stop" block.
However, you can try building a custom subsystem and define equations for the springs and dampers. Then, you can use Simulink blocks to implement these equations. By connecting this custom subsystem to your main system, you could to replicate the desired simulation.
