 |
|
Has anyone seen the video of Sebastian Buemi's crash in practice for the China GP??
Both front wheels explosively sheared from the car going in a straight line.
What the heck??

I saw that. The whole front just exploded. Lucky to not get hurt. I think they are going to put the old setup back on.

| I like how he tries to steer out of it. |

It's supposedly a chain reaction. Failure of the first side caused the immediate failure of the second.

It is being reported that the RF upright failed causing the LF upright to fail . That also caused the front wheels to go flying as the tethering was attached to below where the uprights failed. glad Buemi is OK . Do the F-1 teams still MAGNA-FLUX the suspension components ? Could have been a bad deal if it had happened on race day .
Just a reminder to karters ; Go back to RR section and review the sticky on top reguarding Tethering on all components Better safe than sorry.

| Looked like a three stooges act when the tires and suspension just parted ways. Love the steering input with no tires. |

Bob,
The suspension components are all carbon fiber now.
Magna flux would not help.

John : Do you know how they are inspected for structual integrity?

Yes they do. This was a brand new design that failed and they've gone back to the original design. This is what happens when they make you test at the event. In prior years this probably would have happened at Valencia or Jerez in a test prior to a race weekend. Glad to see he was OK.

Hmm ? ... ALL is a sweeping statement !
I will be surprised if the uprights are CF.
I know the net is not the ultimate data source , but ...

So you are saying that magna-flux is going to work?

Magna-flux is intended to detect cracks or similar flaws in a part. Most inspections - magna-flux, edi-current, etc. - are intended to find flaws such as cracks or manufacturing defects in a part.
If the design makes it through the design review process and it's built per design - it's considered to be good. If the part wasn't designed properly, there isn't a post manufacturing inspection know to man that will detect that defect. Only testing can detect a bad design.

In ferrous metal Tim. As I am sure you know.

No.
I was merely pointing out that it is very unlikely the uprights are made from CF
There are plenty of techniques available for detecting flaws in non ferro components, however, i agree with Tim that there is no inspection method to detect poorly designed or under engineered parts.

I'd reckon that if they could have got the parts on a flight to the UK they would have already sent them back for failure mode analysis. But at this point they may be hard pressed to get back in the next few days at all. In past years there are freighter flights from Heathrow, Munich and Malpensa. I understand from a DHL press release they use 5 747 freighters. I appears all those airports are closed as of now. It's only two weeks until the next GP and they typically don't wait until the team returns before they start working on the issues. I'd bet within minutes there was data and details in Milton Keynes so they could get to work. F1 teams traditionally send live telemetry to the engineering staff at the factory in real time.
