View Full Version : Buemi's Crash

Anyone elsee see Buemi's 'incident' this morning??
Fook me, that would have been scary. :eek:

What did make me laugh was that despite losing two wheels and all his front suspension he was trying to turn into the skid, racer's instinct I suppose!.

yeh saw that this morning - couldnt believe it

apart from the wheels fell off is there any insight as to how it happened yet ?

16-04-2010, 03:17 PM
I saw this earlier, couldn't believe it!

I heard they were using some new hubs they'd designed and this was the first event using them, i don't think they'd done enough testing on them!

It would be strange for both suspension simply to fail. Could be brakes failing then hiting suspension.

i thought it may be brakes - that usually only happens to 1 corner though doesnt it

16-04-2010, 05:27 PM
Apparently it happened just as the car when over a small bump in the track so that plus the braking would have caused the weak area in the hub to break

a mate of mine was saying also that because the hubs are made out of carbon fibre, they're strong but can't take sudden shocks is it'll fracture and i think the sudden shock of going over the bump at that speed combined with the braking was too much for the hub to handle

It was the front right hand upright that failed. As soon as the right hand one went it put all the load on the left hand one which then failed.

Yeah the probblem with carbon fibre is that you can't see fractures or cracks in the material. I only know this as the GE90 fan blades are carbon fibre and have to be inspected either by ultra sound or x-ray (Can't remember). Even though it is super strong and light it does have its down falls.

Quote from Buemi:
From in the car it was not a problem. I just lost both wheels.

16-04-2010, 06:47 PM
Haha, I'm sure he'd have carried on to the pits had he not got stuck in the gravel :rolleyes:

His cousin, Natacha Gachnang, crashed her Ford GT in the FIA GT1 World Champs not long after this incident. She has fractured her legs. Bad day for the Buemi family.

Bring back testing, then we might get the new cars to the finish and not have wheels falling off. Totally amazing screw up by the team.

Nice, Think they were testing a new suspension set up.

Nice, Think they were testing a new suspension set up.

I'm guessing it failed testing too. :p

The explanation that one failed, putting all the load on the other upright, doesnt make sense to me. Surely each upright has enough strength to be able to resist the G force that its own tyres load places on it. What extra load is being transferred to the other front wheel that either wasnt already on it, or might not reasonably be expected to be on it in a bumpy braking zone?

PS I am absolutely loving this season of F1 :D

The cars are stiff enough to keep one corner off the ground aren't they? Seems plausible if one corner disappears under braking that the other will have twice the force. I'm sure they design in a tolerance but I doubt anyone would ever expect one wheel to do the majority of braking from a 200mph stop.

16-04-2010, 11:43 PM
Yeah but, the first upright failure, also simulaneously released the force that was being applied to it. Ie the wheel fell off. So what extra force was being transferred to the other wheel? I just have a suspicion that the design was so flawed, that both uprights failed at exactly the same time. Even super slow mo cameras 1/30th second frames pickup both suspensions failing at the same time.

If the extra braking load (weight?) was transferred to the remaining front wheel, surely the weakest link would be between the rubber and road? For example, both front wheels fell off, and the back wheels then locked up and slid. It wasnt that both front wheels fell off, and then both back wheels fell of because of the extra load that was being transferred to them?!

I was just quoting Torro Rosso and they tend not to lie as they are under so much scrutiny.

If you look at the footage you can see the right-hand suspension start to twist every so slightly before the first. After that it's just a shower of fibre.

Pretty scary accident but not all that dangerous for F1 really, given the enormously strong safety cell and run-offs.

Its all good, looking forward to the qualy and race footage anyway :)
