I like it and will try to get the model and play with it. Great work and thanks for sharing!

[@ArnavTapadia]

How would we model a car that can jump?

[@kipsterlah]

In the final assumption i think its supposed to be b1+b2 instead of d1+d2. Please correct me if im wrong.

Typo

[@wijdaneelfadi9958]

What version of matlab you are working with???

[@onsteroidz9100]

There's something wrong with your body moment of inertia value, hence why the pitch angle doesn't settle to 0

I just checked it. You are right. I3 was off by 2 orders of magnitude. I fixed it and reuploaded the new Simulink file which now shows damped response for the pitch. Thank you for your attention and feedback.

Thanks. Can i ask what the equations of motions would be like for a half car model simulating the roll, which can be inputted into the same model? @@mehran1384
