Ive plotted a graphs showing (velocity.time) and (displacement.time) for an automotive damper.

How would I determine the energy a damper absorbs per cycle and the power it dissipates?

Hello sir

Hope you are doing well sir

have you determine the energy of a damper absorbs per cycle and the power it dissipates? Can you please help me because I'm also facing the same problem.

I understand that you want to determine the energy dissipation of an automotive damper per cycle.

There are many types of automotive dampers and they may behave differently. However, the simplest case mathematically is using viscous damping, where the damping force is the production of the damping parameter and the velocity. Energy dissipated per cycle is the integration of this force over one cycle. You can use the "integral" function to compute numerical integration. Refer to the following link for more details about the "integral" function:

In addition, you can also model automotive suspension using Simulink. For more details about this automotive application, refer to the following link:
