how to design hydraulic actuator for suspension system?

Gm! i m working on suspension system, bt i have some problem in designing hydraulic actuator. i want to know about how to introduce hydraulic system in active suspension system, using simulink.

hello! I am also sedigning hydraulic actuator.Can I have an academic discussion with you?Thanks you！

Hi @yu

What is a hydraulic actuator? Does the design involve mathematical modeling?

Do you have any ideas on how to build a hydraulic active suspension model?

I suggest you use Simscape Multibody to model the mechanical part of the suspension. These two examples are some good starting point:

https://www.mathworks.com/help/physmod/sm/ug/independent-suspension-system-templates.html

These two suspension examples don't have any hydraulic components, but you can integrate a hydraulic cylinder using a Translational Multibody Interface block. There are a few example how this can be done:

And then, design your controller, since it's an active suspension system, in Simulink and/or Stateflow.
