Hi, I am Mohamed-Anas a student at MOHAMMED VI POLYTECHNIC UNIVERSITY and interested in working and collaborating on this project

[SoufianeLaebouss]

Hi, Mohamed-Anas if you still interested in the project. I also would like to work on it.

Hi @robertogl what is the meaning of the T and R term from the aerodynamic drag equation. The equation is somewhat unconventional. See the image of the equation attached.
I am trying to form model equations but I can not make sense of this equation. The simulink model does not explain the terms either.

[jrodgersMW]

If you scroll down a bit more you can see the definitions for T and R.

[martinsadab]

Thank you for your prompt response. Got it now!

However, I still do not fully understand the way the block is implemented.
This is the standard equation for drag force in the literature

The simulink block does not capture the square of the vehicle velocity as is common. Could you help reconcile the two equations?

[jrodgersMW]

The full set of equations are here:

Basically the additional terms (P/RT) is the ideal gas law and is used to calculate air density. Doing it this way let's us capture the effect of changing temperature, gas, or operating pressure (different planet for example) without knowing the density. The vehicle speed is included if you look at the above equations. We consider the velocity speed in all directions as well as any input relative windspeed. If the vechile is going straight with no extra wind, w=xdot (vehicle speed). Hope this helps.

[martinsadab]

Yes it does. Thank you again.

Hello Mr. Martin, i hope all is good, i believe you will bring to our team a better solution ad you will provide a good work, looking forward for collaboration. Best, Mohamed-Anas,

Where can I find the help documentation for the vehicle Simulink model generated by Virtual Vehicle Composer? I have questions about the generated model import parameters, such as what is Evn?

[kevinoshiro]

Hello,

Virtual Vehicle Composer documentation is located here:
https://www.mathworks.com/help/vdynblks/ref/virtualvehiclecomposer-app.html

Not sure what 'Evn' is. Env is the prefix for the Environment parameters such as gravity, ambient temperature / pressure. You can send a screenshot if needed.

Thank you

[chaotic-fantasyam]

it's very helpful thank you very much
