This is the first video of a two-part episode.
Model the physical systems of your racecar and learn about the variety of modeling methods that fit your needs. This is the first video of a two-part episode. Sebastian Castro and Christoph Hahn, of MathWorks, introduce a variety of modeling approaches and demonstrate them in Simulink®.
Sebastian describes the differences between plant models and algorithmic models and how to decide which model is best for your situation. Plant models are a virtual prototype of a real physical system that you are trying to model, whereas an algorithmic model is where you can test your algorithms on your simulation. With Simulink you can combine these two types of modeling and use available analysis tools to then further improve your design.
The many varieties of modeling include those using purely data or purely mathematical equations, and then combinations using both of these methods. Sebastian starts by looking at a suspension system using the mathematical modeling method to see how easy-to-understand equations can be used to create a model. With that same suspension system, he then moves the focus away from equations and demonstrates component-based modeling using Simscape™. This is a tool for component-based modeling that uses blocks which have the equations in the background. The benefit of this method is that you do not need to know as much detail about the equations.

Why did you use - sign at the add block that goes to K1 for Xwheel and derivative of Xwheel? It is + sign in the equation

[@ZzzSchn]

Very useful for students! Thanks!

[@fatimazahramessaoud3905]

Great thank you, so useful, please could you do video about FACTS devices and networks

[@colinslavtcheff4525]

14:57 he says we use a sine wave to model the velocity of the road...why does he model the velocity of the road as an input and not the velocity of the car?

[@AldhairGarza]

The velocity/displacement of the car is what you want to measure. The input of the system is the velocity/displacement of the road. You want to know how much does the car move in relation with the road.

[@ajju3236]

we get another equation for Road also right?

[@uetiancivilian05]

can i model a train bridge interaction by simulink? the train wheel should be connected to rail which can be designed as a beam element and then rail should be connected to bridge which is also modeled as a beam element. i want to know the response of the bridge when the train passes through it??????

suwon mas, dadi maksud walaupun setitik

[@NirmalKumar-or3jg]

Very useful session,
@ host- please do not make sounds when the guest is speaking, he is not delivering the lecture to you alone. thank you

[@TheOnlyRaceEngineer]

@Chengyan Pan questions are fine but what's with the 'hmmmm' 'ahaan'

[@myfreeideaworldwide8449]

Thanks fore this program (video), It is very useful.

[@laoludavids]

Also, can there be a possible way to see a 3D rendering of the movement?

[@shankarchikatimari9689]

Sir I need a simulink model on damping of power oscillations using static synchronous series compemsator I need a video for this

[@vantai4148]

can you help me???
model backstepping controller for buck-boost converter in matlab

[@laoludavids]

Hi, thank you for your comment. I'm really interested in plotting a 3D plot of relationship between amplitudes versus a values of Kcar(spring constant) and Bcar(viscosity). Your help will be appreciated. Thanks. Also can I get your email?

[@budapesteBR2012]

what is the software u use to make this images and apresentation??
Good video congrats

[@StormBorn1611]

I did the exact same model as shown in this video... But the deflection of road and car are almost same in my scope
Please help me

[@FireStriker2016]

Did you find the answer? Same happening to me

[@tutran2032]

create shocks on the simulink

[@myfreeideaworldwide8449]

Thanks for this program (video), It is very useful

[@ruke1ire]

awesome!!

[@lohitsk5490]

Weather sine wave is a velocity or displacement component?......Please reply......Thank you

[@muratkar8753]

LOHIT S K sine waves represents vertical velocity of the road. It is shown in the simulink model as well.

[@Impedancenetwork]

That guy on the right needs to just shut up while the guy on the left does the presentation. He should do the introduction then disappear, then show up at the end to conclude. For some reason Matlab thinks we need a guy to occasionally interrupt by saying, "ok", "uhhhmmm", "yup."

[@TheOnlyRaceEngineer]

damn right bro

[@seggyRK]

After every statement the host "mhmm" so agitating

[@TheOnlyRaceEngineer]

why doesn't he just shut up and let the cool guy go through his stuff.
