These videos are invaluable. Thank You. Around 6-7 years ago, I could have really benefited from these specific videos. Bookmarked, in case I ever revisit this subject.
This is exactly the content I’ve been looking for! Fast, to the point information in a way someone that knows nothing about suspension could understand. And, someone that does know suspension can improve. I’m more into off road vehicles with solid axles front and rear if you could do more on that kind of platform. Thank you and keep it coming.
Thank you for free-sharing your priceless hard earned knowledge! I hope me and my co-generation car-guys, take the knowledge from you and guys like you, and pass it to the next generation of car enthusiasts! P. S. Not all those who look for free knowledge are created equal! Sometimes it's not about having or willing to pay, it's about not being able to do transactions internationally for being sanctioned/banned from international banking system!
The thing I love about my old car is that a lot of other folks have already dialed in a lot of the intricacies done the negative camber spindles and changed the anti-squat really like how my old car cuts curves on 50 height ratio radials
For your wishbone example: Im confused as to why the intercection of the control arms and the contact patch are not being tracked during movement. They clearly move and cross independantly in your animation, not tracking the instant center.
Suspensions Explained: Would it be fair to say that a higher roll center will have less body roll (closer to but below the center of mass) but a harsher ride and a lower roll center below the center of mass will have more body roll and a more compliant ride as the spring and shock are absorbing more of the force of a bump instead of that force being transmitted by the control arms into the chassis?
Unfortunately, I have not found a good book on suspension design. There are several good books on Vehicle Dynamics, however. I recommend "Race Car Vehicle Dynamics" by Milliken and Milliken and also "Fundamentals of Vehicle Dynamics" by Gillespie. The former is considered the bible of Vehicle Dynamics and you will find it on just about every vehicle dynamics engineer's desk.
Hi, could you please tell how you build a knuckle wireframe? I understand it is a 3d sketch, but I can't figure out what constraints you used. Thank you.
I'm a idiot but i found out about this and it became a core issue in the MR2 Community because of one guy who revolutionized it for competitive practices, leading to a lot of very competitive MR2s in the 2010s that also were sweethearts, joyful, amazing to drive when the standard (SW20 mainly) has serious flaws. My shortest take is its a naming issue, if this was just "Camber Change" and "Camber Change Multiplier" everyone would understand it. There IS a lot more going on obviously, as going too low sounds like a easy solution from a vehicle driving dynamics if not a max potential dynamics (i mean for the rear generally, on rwd cars), but at its core the subject is one where a weird engineering name alienates what otherwise should be a simple enough concept to grasp.
I read a book where they described the BMW telelever suspension anti dive with instantaneous radius. But I guess you have to make a video about it for me to understand :D
hello sir can you post a series on DESIGNING A SUSPENSION GEOMETRY FOR A FSAE CAR - DOUBLE WISHBONE, DAMPER TO LOWER ARM TO BODY or PUSH ROD SUSPENSION, I will be waiting sir i request you sir
I have gone through so many frustrating videos about rolling centres. This is the best of the best. Standing Ovation 🎉❤
These videos are invaluable. Thank You.

This is the content I crave.
This is what I call a quality information.
Fast, detailed and clear. Thank you!

This is very insightful and exactly what I was looking for. This is a very good presentation. Thank you very much!
Subscribed, will view Part 2 before asking questions, I suspect you will cover what I want to ask.

Wonderfully explained 👏. Thank you
very nice explanation thank you for that

so awesome - is there a way to get the models to play around with them?
Top!Thanks!
What is you desk book for suspension design?

great video and and explanation! thx a lot.
pls can you share the file cad of this model ?
Beautiful
Nice!
Fast car physics.. is a good book Chuck Edmonson
I can probably do this in excel, and that fact scares me.
hello sir can you post a series on DESIGNING A SUSPENSION GEOMETRY FOR A FSAE CAR - DOUBLE WISHBONE, DAMPER TO LOWER ARM TO BODY or PUSH ROD SUSPENSION,
I will be waiting sir
i request you sir
That's an engineer right there, not a mechanic.. taking nothing from mechanics of course.
like if you are watching this for FSAE
