Having been subscribed to your channel for over a year now, I've come to expect this quality in your videos. Yet it's worth reiterating how damn good you are at tackling complex concepts that no one else dare touches, managing to break them down and build them back up from simple fundamentals, and all of this while always finding the right balance between not losing your audience to unnecessary complex waffle while also not dumbing down the content quality. Your work is greatly appreciated, Stuart!

[@falinestixiaolong9691]

You're damn right. I had just watched before that a video on the official F1 channel about the exact same topic. The guy explaining may have been an expert but his diagrams were not clear, and throwing words like "anti-roll bars" without explaining what it is don't help, so in the end I didn't understand anything.

[@mohamedsalahdimessi1721]

I can hear u explaning f1 concepts for hours, cheers.

[@001thefish]

This is incredible. It feels like you can watch the sport for decades and never learn anything about how the suspension works. These last two videos have taught me so much about things I'd heard about but never really understood, and it only took 20 minutes.

[@swanner95]

I love this channel's contrast between in-depth understanding of the fundamentals of an F1 car, postulations about race and championship rules and arrangements, insights into the teams and their objectives and challenges and of course, tactfully placed aubergines during the season reviews.

[@MikeeCZ]

4:00 Forgot to mention side wall flex, so not as squarely as possible, the tyre should still have negative camber even after taking the roll into account to counter the tyre deformation due to all the lateral forces. The faster the corners & the more the downforce, the larger the camber. Also good to mention that rear tyres tend to have lot less or no camber at all. This is the trade off between cornering grip and acceleration grip as the rears are the powered wheels in case of F1. (FWD cars tend to have very aggressive rear camber as the rears main job is just to corner)

[@DaylightDigital]

Love everything about this except for "shifting center of mass." Dynamic load transfer due to acceleration, braking, or cornering is not caused by the CG moving around.

[@jozsefmolnar6453]

Yes, absolutely. You can have extremely big weight transfer without almost any chassis roll or CoG movement.

[@DaylightDigital]

@@jozsefmolnar6453 I stopped using the term weight transfer years ago precisely because it's misleading. Load transfer is more accurate and less ambiguous.

[@itstimeforham]

This has blown my mind. I didn’t really understand suspension until watching these two videos. Huge kudos to you, and thanks.

[@draconicdusk5911]

Mind blown, so much useful information. Liberty media really should hire you to make explanation videos like this on F1 weekends.

[@JimTheFly]

I've been a racing fan for years but this is the first time I really fell like I can start to understand all the various suspension-related terminology. I'm not sure I can properly use it in my racing games YET, but I feel like I'd be a lot less random in my setups at least.

[@mooosje]

I didn't understand 90% of this video as i wasn't paying full attention, yet it was still so entertaining. Definitely will be rewatching later on to see what I missed :p

[@markmcnaughton85]

Here you are explaining things in a way that is only going to further invest me in race weekend discussions. You always seem to strike the right amount of technical knowledge for me personally and I applaud you for that.

[@oscarshen6855]

Under current regulation the fat tires do most of the work that should have gone to spring and damper. In 2022 they will use slimmer tires thats more raletive to road cars, they can't absorb as much energy as current tires, which means the suspention needs a full redesign.

[@Timberwolf69]

A redesign? Not really. Some adaptation, yes.

[@billyindiarto7209]

Have been wondering all this time what a heave spring does. Now I do. Thanks to Chain Bear. Awesome

[@288gto7]

3:20. those arent packers. They are just bumpstops. Packers or „spacers“ are small cylindrical things that slide under the bumpstops so that the car will hit the bumpstops sooner. If you want a detailed explanation watch aris drives and fatcad motorsports videos on bumpstops

[@Timberwolf69]

I've seen packers in NASCAR, but those usually are wedged into the springs at a certain point to change the stiffness of that spring.

[@fredherfst8148]

Well done. I finally get a grip on suspension. My takeaway is..holy shmoley...so many design and setup variables, all more or less interacting and specific to a course...mind blown again.

[@someonespotatohmm9513]

I think a video about the regulations about the suspension could be interesting. I never understood why all the new suspension innovations that diver to much from the current setup are prevented, seems like you could do a lot of interesting developments in this area.

Can you do a video like: "Was DAS any good?". Would be interesting!

[@B3AN5]

If Mercedes used it in 2019 and 2018 it would have made winning the championship a lot easier as it allowed them to go fast in the corners and on straights without compromising set up, but because they were ridiculously dominant this year they didn't need to do it

[@GregBrownsWorldORacing]

Thanks Stewart, I wanted to know more and nowI do

[@brianb-p6586]

@2:29 you say that the centre of mass shifts under braking. While a tiny bit of that occurs, it is completely insignificant. Load transfer to the front under braking is not due to shifting mass... and any dynamic load shift (to the front while braking, to the rear while accelerating, to the outside while cornering) is not due to any change in the position of the centre of mass.

[@Jon1998109]

Centre of mass doesn't change under braking. The braking force causes a torque which is then balanced result in an uneven load of the car

[@1985NathAtul]

a better driver..is better than tons of setup i learned a lot of setup and master it but still cannot control the car

[@ronanoboyle6348]

Load a few time trial setups for a few different tracks and you’ll notice a trend for most tracks. Lower front aero higher rear wing. Softer front springs and front sway bars. Stiffer rear suspensions and rear sway bars. Usually about 1-3 front and 7-10 rear( for suspension and anti roll bars). Ride height 2-3 or 2-4 Suspension geometry usually either right left left left or right right left left. Tyre pressures as low as possible. Basically just get a baseline set up from time trial and tune it to your liking

[@samnotloading6101]

In 2020 downforce is really good for time, highly recommend more downforce than previous years

[@FormulaTurismo]

This was great. Thanks Chain Bear. Could you do a video on the tunned mass damper that Reaunlt invented in 2005? I would love to see that.

Excellent presentation!

[@nikoyochum6974]

quick note, I don't believe that the center of mass changes under acceleration, there is just a load transfer, the center of mass is a constant point.

[@robin111v]

Next up suspension geometry? I know depending on if you have the arms as a parallelogram or different you can have a constant camber or dynamic, same for the steering rod actually (so you could force more toe in the corners). I have no clue what the rules are and how much teams (want to) use that, but i am very curious now :)

[@Thesupremeone34]

you can never have constant camber (sad i know) if you look at the front view and extend the lines of the suspenion arms, they will meet at a point far away from the car. For suspensiuons that don't have much travel like an F1 suspension, a circle with the radius from this point, called the front view instant center, to the center of the wheel *very very* closely approximates the true suspension travel. Bigger radius, flatter effective arc, less camber gain in travel. tow gain in steering is called ackerman steering geormetry. I don't work on steering so all I can say on that is all steering systems have some amount of ackerman and how much you have is controllable by setting the mounting point of the tie rods farther or closer to the axis the wheel rotates about. How much toe gain you want is entirely a factor of tire data and load transfer in steering, and sometimes you even want toe loss, so there's a lot to figure out there.

[@Thesupremeone34]

actually i thought about it a bit you can have constnat camber over a small region if you are willing to have a lot of scrub, which is the wheel moving inward or outward as it swings. Camber gain and scrub are trade-offs that are balanced by the designer. roll camber (camber gain in roll) is based on maintainting the largest possible contact patch as the body rolls (yes, your middle school science teacher lied to you, surface area affects grip a lot) the track width of an axle (center to center wheel distance) affects the load transfer in cornering, the smaller the track width, the more load the outside wheel sees and the less the inside sees. Most suspensions scrub inward as the suspension moves up. Some will also scrub inward as it moves down but most scrub outward. Ideally, the track width doesn't change in roll but usualy it will get smaller. You want the camber gain at a specific roll (say a 4g corner) to be just right so the tire deformation from being pushed sideways by the centripedal acceleration of the car, combined with the camber, gives the rectangualr contact patch. You also want the track width to be as wide as you can get it because unnecissary load transfer is bad for the outside tire's wear life.

[@brcros]

@@Thesupremeone34if RB18 & 19 have a upper mono arm that is used as direct antiroll bar, and optimized the tyre contact on both side, I guess every team will adopt this way sooner.

[@Thesupremeone34]

@@brcros that is some faith in the pin that holds it in. in a double wishbone suspension, when it is "solved" your output is two lines floating in space near the chassis. these are the axis that each triangle formed by the arm pairs will rotate about. the inboard points of the upper and lower arms can be anywhere on their respective line. it doesn't matter how wide or narrow the triangle is, just that those points are on that line that it needs to pivot about. the wider you make them the heavier you're getting since the bars are longer, but the more rigid it is. (half the bar is also unsprung mass which is something you want to avoid raising). there's nothing stopping you from using one bar on a hinge instead of two bars on ball joints. effectively its the same as having two small bars very close together. given how little they move in f1 you might????? even be able to orient the beam with its most flexible direction parallel to the line and have it flex? since you have one bar centered like that, yeah, you can do an arb super easy. just hop across. that tire contact comes from the orientation of those relative lines.

[@QemeH]

I'm just waiting for the next big step in suspension evolution: _Predictive_ Suspension Under the current rules they would be illegal, because changing setup during a lap is heavily regulated, but computer power should theoretically be there to not only load a profile, but rather gain live data from the car, which is then cross-referrenced with the position on track and gives an optimal suspension setup for the given situation.

[@ropre4FA]

[@AviAeroAsis]

[@srinitaaigaura]

Stiff is not always more stable. If the suspension becomes too stiff, the car will bounce so hard the tires start to leave the ground and lose contact. This can lead to loss of control.
