Wow... magnificent stuff. Geometry makes rigidity.. now I get why honeycomb aluminum core is so important in Carbon monocoque designs

“Slam and Jam!!!”

9:37 Which book is he mentioning ?

Excellent video here. Must be made required viewing to any FSAE participant. As a past FSAE competitor, I have to second the professors lament about driver ergonomics. It gets neglected. Secondly, coming full circle from drivers back to tires; teams with tall/heavy drivers (ave american male…) will be needing 13” wheels to fit all the ither stuff (brakes, bearings, linkages) However, challenge yourselves early on. Teams would do well to strive for small/light driver selection (yes, it is an exclusionary process), and heavy consideration to 10” wheels, it makes design of everything else more challenging, but you will require a smaller engine, have a lighter overall car (@ minimum wb) and if all done well you WILL WIN the events that heavy larger wheeled cars cannot win. My team ran 13”/8”wide hoosiers. They never got warm. 7” wide barely after 30 min of autocross. Also i’m 6’3” I could not confortably fit my feet in the pedalbox. Failure. FSAE WAS FUN!

I'm not done yet❤❤❤❤❤❤ Triangles are engineers best friend 👍👍👍👍👍👍👍👍

Nice

Really cant stress enough just how good your race videos are. I came from baja then autocross before i found the king of absurd racing. Race mowers. No suspension. Limited quality tires. NLMRA rules. Looking at your green kart learning tool is a great example for front end geometry. People dont realize what suspension does for you till you take it away.

reverse engineering (drawing) a (green) circle into a higher dimension (3? higher?) circl3 (circl4...) (orange delineated oblong object.... I think it's 3D with a projection behind the monitor. Cool !!

What about shocks that let you independently change fast vs slow damping control on both compression and rebpund? Is that a thing that's possible?

That 1:2 ratio goes completely out the window for long travel suspension like those found on desert trucks, though. No way in hell could you make a 60-inch travel spring and shock to handle 30-40 inches of suspension travel. Where and how the hell would you even package all that?

Do you define track width as wheel mounting surface to wheel mounting surface, or from the outside edge of the tire to the same on the other side? Depending on tire width and wheel offset/backspacing, this could make a huge difference on the accuracy of someone's track width to wheelbase ratio. *EDIT:* Lol, I had paused the video to ask my question literally 4 seconds before it told me. Nice. (It's center to center of the wheels BTW, for anyone watching. So technically neither of my examples unless the wheels also always have 0 offset.)

Give it a de-Dion axle rear suspension for 2024. Particularly with a Satchell-Link style triangulated 4-link.

Won't work to open all the way. Parts overlap

😱 *PromoSM*

how to try trial?

Good job man thanks.

What about a dual clutch transmission

Is it posible to upload on 720 or 1080 pixels?

What about changing theses angles by actuators in realtime ?

Getting ideas for poly bridge

Thank you so Much for this

I am convinced that kingpin inclination and caster are utterly alien concepts to every single Red Bull Soapbox builder!

This should be compulsory watching for Red Bull Soapbox builders!

What a treat to watch a presenter who really knows what a space frame is! My two go-to modelling methods are soft soldered brazing rod and hot melt glued drinking straws - they'll quickly show you any missing triangulation.

How can I get it

Is there a way of figuring out how far apart the pivots need to be to achieve different angles? Thank you!

Thank you very much professor

.....[terrible camera view!!...]

Great demonstration! My only objection is if you are loading the inside front more, it means it will be rolling more as well. You're going to get the same amount of weight transfer dynamically regardless of caster setting... But with the outside wheel naturally moving upwards, and inside moving downwards, it's giving more roll motion into the chassis. You're basically changing the individual ride heights a small amount like shortening and lengthening the legs of a table. This also equates to more body roll in the entire chassis (assuming >50% front weight distribution like most cars). Front wheel drive stuff in particular is very sensitive to caster changes, and in my experience when making a big change, it also affects the rear camber angle since the body is now tilting over further. Generally to maintain balance (if desired) a small adjustment out back is needed. More caster allows the wheel turning forces to peak sooner than actual grip peaks, but also stronger through the steering wheel. It makes the car easier to drive at the limit, and as you said especially under hard braking.

So much information in 5 minutes!! This is truly impressive, thank you so much

Got it, on a positive Caster angle, the wheel contact patch follows the the “Axis” of the steering pivot point.. and not the pivot point itself.

He is like a knowledgeable Dad, I’m 30 and starting to get into cars and design… 👍

where i can download all this part?

very good. thank you

Ornithopter time

Mini coper sof top comvrtabel working video plzzz😢

It looks like the feet barely clear the floor. It's almost sliding.

hinges left the chat

Finally I can get rid of my graphing calculator!

What book he is referring to here? 9:37

If you really wanted to educate, you'd at least say that it's Jansen's Linkage rather than implying you came up with it.

It faintly resembles a frontal leg joints of quadruped animals for some reason.

Maxed my volume, can't hear you

Incredible series- thank you! you've breathed new life into our project by setting things straight. As a complete beginner creating a great car, your info is invaluable! thank you again!

Another great video thanks 👍
