Well Raikkonen is going to love that if true as it is noticeable he has done better this season with the push rod system,
Those info are wrong.Ferrari will maintain a push-rod suspension on the front.Moreover according to F1AT,that is a really reliable source,Rory Byrne is working hard(from a cuople of weeks) on the chassis side and helping Simone Resta on the mechanical side,in particular on the rear suspension,which was the biggest problem of the sf16-h.I'm sorry about my bad english but i'm italian,i hope that all of you can understand what i have written.
Yes.FerrariHeart wrote:Those info are wrong.
But not this year. The main point of the suspension design naxt year will be the hydraulic third element to control the vertical movement like Merc is doing it. This is already a problem with the push rod and Merc exploited a loophole in the rules to fit the element to the chassis.Paul wrote:Keeping Ferrari speculation threads busy since 2011...

Recall that Haas makes substantial use of Ferrari technology and "expertise," especially as it relates to suspension components.[url=http://www.f1technical.net/forum/viewtopic.php?p=578777#p578777]bhall II, Apr 27, 2015[/url] (edited for clarity) wrote:Fernando Alonso is widely reputed to favor a car that tends to understeer rather than oversteer. From his perspective, that means the front suspension isn't quite as important to his overall setup as something like throttle response, or driveability, because he expects the front-end to give up on corner entry, and more so than using the steering wheel, he uses his right foot to rotate the car around the apex.
That also means he may not be particularly sensitive to potential flaws in the suspension unless something goes horribly wrong.
Kimi Raikkonen, on the other hand, is much more sensitive to the front-end, because he wants it to be as planted as possible...
I think it might be somewhat telling that after three years of pull rod layouts that more or less looked the same, SF15-T's layout appears to feature substantially more robust components. Since designers tend to want such components to be as thin as possible for aero purposes, there must have been a compelling reason to change.Kimi Raikkonen via ESPN, Nov 13, 2014 wrote:Since the go-karts, if it doesn't turn and the front doesn't bite I've never liked it. My driving style is more about trying to carry the speed into the corners and keep it up in the mid-corner. It's the way I'm used to doing thing but obviously it changes every year and with every car, but I still think it's the fastest way and when you get the car working for you as you want the fastest maximum speed - for me at least - can be found that way.
It's something that's lacking from [F14 T] right now and if you cannot put the car where you want and brake where you want because of locking or sliding the front then it becomes a guessing game about where you are going to be. And if you miss a little bit the corner you are going to miss a lot of speed on the next straight. It sounds like a small thing, but around one lap when you keep guessing every corner it creates quite a big deficit. A few races it has been pretty okay and then most races it has been like that where you fight every corner and then the time difference is quite big.
Enter: installation stiffness.DaveW, Nov 19, 2013 wrote:"Installation stiffness" affects the efficiency of a vehicle suspension. I have yet to see a pull rod suspension that doesn't give away installation stiffness compared with an equivalent push rod layout (mostly F1 & Indy). I'm not completely sure why, but I did invite a FFord designer to bring his pull rod car (he claimed better c.g. height with no loss in suspension stiffness) to my rig a couple of years ago (I think). He didn't, but I haven't noticed too many pull rod cars in UK FFord grids recently.
F1 designers always insist that no lap time was ever gained by mechanical suspension changes, and they have biased regulations to ensure that is unlikely to happen soon. This is stark contrast with teams running junior series who pay great attention to mechanical set-up - but their ability to make aerodynamic improvements is limited.At the time, I didn't realize James Allison had already confirmed the existence of a fundamental problem...bhall II (continued) wrote:gato azul, Apr 11, 2012 wrote:...one issue here is, [with poor installation stiffness] that you end up with a spring at "end of the chain", over which you may don't have any control in terms of damping. Now if you manage to get this spring into resonanz, you can face a complete loss of control over contact patch loadings, leading to a massive, sometimes sudden reduction in grip, under certain condition ( for example in a certain (car/bike) speed range through corners).
Another issue here, is that with a spring element you always induce some lap/delay in your overal system response, and this may shifts with exitation frequencies.
In simple terms the difference in time (lag or lead) between the peak of your spring force and the peak of your damping force, in a simple mass, spring, damper system.Autosport on the 2014 USGP wrote: Kimi Raikkonen says he hates the situation he finds himself in with the handling of [F14 T] at the moment, following a disappointing US Grand Prix.
The 2007 world champion came home 13th and one lap down on race winner Lewis Hamilton at Austin on Sunday, as his race was marred by front-end problems that plagued him all weekend.
"Here was again one of the most difficult weekends," Raikkonen told reporters after the race.
"Japan was similar - we fight with understeer the whole weekend and whatever we do we can't seem to get rid of it.
"Then you can expect in the race to destroy the front tyres.
"Obviously I hate the situation the way it is and the way things are going, and I cannot solve it by myself."
Raikkonen added that the main frustration with his problems was that he and Ferrari have been unable to pinpoint what is causing them.
"To try to drive slowly in certain places didn't make any difference [to the life of the front tyres] so I don't understand it really," he said.
"Wherever we finished it's pretty disappointing. Not being able to solve certain issues is frustrating.
"Hopefully something comes up and we find what the issues are.
"I appreciate some help and obviously we try to help each other to fix these issues, but if we knew the issue it would be easier to solve."
The Finn said that team-mate Fernando Alonso - who finished sixth - is not as sensitive to the front-end difficulties with the 2014 Ferrari.
"In certain places, yes, it's the same issue, but I think [Alonso] doesn't mind too much when the front is sliding," he said.
"So the effect is not so big then. It's a bit of a different story."
ALONSO BATTLES VIBRATIONS
Alonso only just held onto sixth at the end of the race, beating Sebastian Vettel to the line by half a second after his car developed a serious vibration in the closing stages.
"I had huge vibrations on the tyres for the last two laps," said Alonso. "I could not even see the track, basically.
And Alonso recently all but confirmed problems with the front suspension during his tenure with the team...Sky Sports, Aug 23, 2014 wrote:Speaking to Sky Sports F1’s Ted Kravitz at the Belgian GP, Allison said that even though the Scuderia have worked to minimise the Finn’s discomfort with his F14 T, the issues are a consequence of the car’s design and therefore inherent.
“We’ve improved things throughout the whole year,” Allison, Ferrari’s Chassis Technical Director, said. “The car is much more to his liking now than it was then, but there are certain fundamental characteristics that are sort of ‘baked in’ to a car when you lay down its architecture.
“That architecture is not really modifiable in a given year. You can make it better, and we have made it better, and we continue to make it better. But there are limitations.”
Rewind back to 2011, when Ferrari was apparently unable to reproduce Red Bull's anisotropic front wing...F1T, Sep 6, 2016 wrote:“On the other hand, some odd things happened to me. Some blamed me for everything, for example that the front suspension did not want to work,” concluded Alonso his honest assessment and recall about his time at the most successful F1 team.
In order to be effective, flexible bodywork such as this has to be constructed so that neither drag force (horizontal) nor downforce can independently flex the wing. A wing that responds to drag force would be mostly pointless, and a wing that responds to downforce will flutter (as seen in the image).
Fast forward to this season...

By extension, it's very difficult for me to believe that problems like this are isolated; on the contrary, it points to structural design and/or manufacturing woes that have the potential to screw up everything.

Grosjean said that Haas made changes on Friday night at Circuit de Catalunya, but they weren't as successful as hoped.
"We changed the philosophy of the set-up we'd made for China so this should bring the car back to where it was but actually it didn't happen as much as we wanted," he said.

Love those threads (non sarcastically). At least there can't be "it's last year's car!", only "last year's car with new tyres and wings".
I too believe that at least some of Ferrari's problems are structural. The question is, are the problems caused by engineering mistakes, or by managerial mistakes? I think it's the latter.bhall II wrote: .....
Examples of problems that can be caused by insufficient or erratic stiffness:
Any of those seem familiar?
- Chronic setup difficulties
- Inconsistent development, both mechanical and aero
- Poor low-speed traction if the suspension is stiffened to correct high-speed balance issues
- Bizarre race strategy born from an inability to understand the tires
I believe Ferrari's technical problems are structural.
Naturally, I can't confirm if any of this is right or wrong. However, it's 100% plausible, even though it would seem to be a failure of something so fundamental that most folks probably wouldn't expect it to happen at "the pinnacle of motorsport."
