Why is the suspension displacement so low?

hello everyone,

I designed an active suspension system but there is something I don't understand. While the bump in my road profile is 0.07, I see the suspension movement as 10^-7. Of course I expect improvement, but isn't this too much. Please I am waiting for your comments.

Hi Kerem,

Your active suspension system's response appears unusually low, possibly due to issues in your model or simulation setup. Check the following:

• Verify realistic spring rates, damping, and actuator dynamics.
• Ensure the controller is correctly tuned.
• ]Confirm realistic actuator constraints.
• Use appropriate time steps and solver configurations.
• Consistency in units is crucial.
• Ensure correct measurement of suspension movement.
• Accurately represent any nonlinearities.

These checks should help pinpoint the cause of the discrepancy in your simulation results.
