You'd put an accelerometer on the seat, to measure the vertical accelerations the spine is subject to. You integrate the signal over a short period of time, using existing health and safety data, and transmit that to race control. If the car exceeds the limit, it gets a penalty. Simples! Much simpler and to the point than trying to police a ride height, and a nice engineering challenge.Tommy Cookers wrote: ↑07 Mar 2024, 16:38put a 'g' sensor into what ?

This specific accelerometer is already there as part of TD39 from 2 years ago.izzy wrote: ↑07 Mar 2024, 18:53You'd put an accelerometer on the seat, to measure the vertical accelerations the spine is subject to.

Yes there are accelerometers all over the car and I was expecting there'd be one for this already, but George and Max seem to think not.
Yes indeed is there and it seems it doesn't go over the limits that FIA has there. If it was passing the limits, isn't FIA job to intervene if they pass this limit?dialtone wrote: ↑07 Mar 2024, 19:10This specific accelerometer is already there as part of TD39 from 2 years ago.izzy wrote: ↑07 Mar 2024, 18:53You'd put an accelerometer on the seat, to measure the vertical accelerations the spine is subject to.

Oh yes, tho TD39 has been dropped now apparently. It was an AOM Aerodynamic Oscillation Meter, to combat the porpoising, and now they've decided that's not a problem any more. So they could reintroduce it, and it sounds like they should really.dialtone wrote: ↑07 Mar 2024, 19:10This specific accelerometer is already there as part of TD39 from 2 years ago.izzy wrote: ↑07 Mar 2024, 18:53You'd put an accelerometer on the seat, to measure the vertical accelerations the spine is subject to.

Rake wasn't there for the floor and diffuser, it was there for the splitter, bargeboards and front wing most of all. Raising the rear brought the front wing almost completely down on the ground, maximising ground effect. Rake also meant the whole car was at a higher angle typically, including rear wing, so everything could have been balanced nicely.vorticism wrote: ↑07 Mar 2024, 17:37How low were the planked cars prior to 2009? Rake helped in various way, I don't recall the plank scraping the ground much from 2009 onward, so in that era it was more the aero forcing a safer/comfortable ride height and not the plank.
Two off the cuff suggestions:
-omit the tunnels, keep the rest of the car the same including the large diffuser. This would force the teams to use rake again.
-keep the floor generally the same and somehow mandate a raked plank/center floor within the current framework.
Rake ensured that the front edge of the t-tray generally contacted the ground and kerbs first, and kept everything aft of the t-tray higher, helping protect the driver and the engine.
Because it's faster with it low, so nobody will do that. Just the same as nobody would run a halo if it wasn't forced upon them because it's extra weight.bluechris wrote: ↑07 Mar 2024, 14:32I don't really understand the fuss about the ride height and the drivers feeling really? any driver who feels bad of the car he drives, he can speak to his team to make it not so stiff and to ride better. Why all this discussion? can you elaborate?
If the team dont do that, its their problem to solve.
Exactly, same as a F1 car should tend to use active suspension to improve perfomance without the usual negative comfort connotations of passive system that are good for perfomanceStu wrote: ↑07 Mar 2024, 09:40A Toyota Corolla will tend to use active suspension to improve the ride quality for the occupants without the usual negative performance connotations of a passive system that is ‘good’ for ride quality.Andres125sx wrote: ↑07 Mar 2024, 09:22
Interesting quotes!
Only way to solve this is...
It´s nosense that we can have active suspension even on a Toyota Corolla, but F1 can´t use it
That´s what F1 teams do, slowing their cars down on purpose for driver comfort
When DF was limited because some drivers started to feel dizy due to high lateral G forces... do you think rulemakers should have kept those rules, and it was F1 teams who should limit DF theirselves to keep drivers safe? That is utter nosense. F1 teams job is building fastest possible cars within current ruleset. If safety is at risk, it´s FIA job to modify rules to ensure drivers safety
An F1 car will only use active suspension to improve car performance with no consideration of the effect on the occupant.
The only time since the discovery of the power of GE in F1 that a driver’s comfort has been considered is with the Lotus 88, and that got banned…
Because of the G forces on the car, not because of the active suspensiongshevlin wrote: ↑07 Mar 2024, 23:11Allowing active suspension systems is a superficially appealing change, but the suspensions will still be stiff to keep a uniform ride height. They will allow much faster cornering speeds. When the systems were at their peak on the 1992 Williams, Nigel Mansell admitted that his eyes were "wandering" through fast corners because of the G forces on the car. That is one step below G-LOC, which nearly led to disaster at the 1999 CART race at Texas Motor Speedway, until Steven Olvey got drivers to admit they were suffering G-LOC in qualifying, and the race was cancelled.
Human beings, even young and very fit athletes, still have body limitations that must vlbe respected.

What Toyota Corolla has active suspension?
Why not bring back 1982's laser-enforced 60mm minimum ride height rule?
I feel like teams would find a way around that to a degree. Like the flexi wings most no matter the tests they did they could get them to pass a test but flex more under load feel like these days someone would find that loophole again- as your indicating a little alreadyJordanMugen wrote: ↑08 Mar 2024, 09:33Why not bring back 1982's laser-enforced 60mm minimum ride height rule?
With active suspension now being banned, the obvious cheats used back then (like driving on track and dumping hydraulic pressure to immediately lower the car) should no longer apply, no?
So the minimum 60mm ride height, should in theory, be able to be rigidly enforced both before and after sessions?
Would this encourage soft rate passive suspensions (perhaps on the heave springs I dunno) so the car gets dumped onto the ground as soon as aero load is applied to it?
Theres no "magic" in active suspension. Given a low movement to keep chassis consistent height from track surface, then tbe forces are effectively the same for the same car/load concept. It's just a control of tbe total kinematics restricted to the same range in millimetres.Andres125sx wrote: ↑08 Mar 2024, 08:56Exactly, same as a F1 car should tend to use active suspension to improve perfomance without the usual negative comfort connotations of passive system that are good for perfomanceStu wrote: ↑07 Mar 2024, 09:40A Toyota Corolla will tend to use active suspension to improve the ride quality for the occupants without the usual negative performance connotations of a passive system that is ‘good’ for ride quality.Andres125sx wrote: ↑07 Mar 2024, 09:22

Passive systems need to be extremelly stiff to keep ride height and rake/pitch as constant as possible to not reduce ground effects with those variations. That means confort is non-existant, F1 cars run almost with no suspension at all.
Active suspensions would allow keeping ride height constant, but still usefull suspension wich damps the bumps and do not torture drivers
