Modeling of a Continuously Variable Transmission (CVT) BAJA All-Terrain Vehicle (ATV)

[@aviralojha5412]

Will you provide a basic video of using matlab and simulink for CVT tuning?

[@darshanoza1063]

Hey did you find one?

[@pavitraj311]

What is the value of initial velocity and Engine inertia in the generic engine component and if you have selected no inertia then how did the engine component works

[@alakshendraveer]

Hi Pavitra. I hope we have discussed this on call and you have the answer now.

[@pavitraj311]

@@alakshendraveer yeah but this comment is older than the call

Can we calculate the RPM of primary using the CVT ratio

[@marcoslealporto]

Good evening, Ive been adapting your model to fit my teams baja project. In our car, the cvt comes directly after the engine, and when i try to swap the gearbox and cvt position to match it, the simulation stops working. Other changes that I did to the model showed no problems at all, so Im kinda lost. Can you guys help me? Thanks in advance, and great video!

[@alakshendraveer]

Hello Marco, Thanks for checking the model. We can definitely help you. In your case, you need to tune the model a bit. I would suggest you to share more details and the models on [e-mail] via email. We will have a look and help you tune the model. Thanks, Veer MathWorks

@@alakshendraveer it was actually a problem with the inertia of the CVT that I ended up putting some messed up values haha. Thank you for you help and if I end up having any more trouble Ill let you guys know. Thanks again for the awesome service and support

@@marcoslealporto Hey Marcus, can I send you a private message? I am a member of a BAJA SAE team too, and I have some doubts about the inertia on CVT

Hi, can you share the closed loop CVT model?

[@jayshah900]

sir, CVT is directly conected to Engine right? but you have connected GB before CVT

[@alakshendraveer]

Hi Jay. Yeah, you are can do that. In fact you can remove the GB and place it after the CVT as you see in actual BAJA vehicles. Try that and reach out to us at [e-mail] if you face any issues.
