I agree with this.
Honda will have ADUO upgrades BUT:
- they need first to fix vibration
- so I fear they will not use the ADUO performance upgrade, at least the first
Hence they will fix vibrations and finish races but with same pace than now
That's not how it works. Fixing vibration in itself means a lot more usable power.
As per Honda the vibration fixes don't apply to the homologated parts. I suspect that those metal bars that connect to the heads and the section of the ICE that connects to the chassis have engine mount like characteristics that teams still use various damping strategies nearby.
In Formula 1:
monocoque β rigid titanium mount β engine β gearbox β suspension
Because the engine carries structural loads, any soft mount would ruin chassis stiffness and suspension geometry.
1 - Where damping can happen
Teams can still control vibration in several ways:
Tuned mass dampers
Small masses attached near structural areas that absorb specific vibration frequencies. Example concept related to the well-known system once used by Renault F1 Team.
These can be installed:
- inside the engine cover
- on brackets near the PU
- sometimes on gearbox structures
Structural damping in the mounts themselves
Those triangular links are often:
- Titanium
- thin-walled
- carefully shaped
Their geometry can be tuned so they flex microscopically to dissipate vibration energy.
Think of them as very stiff spring elements rather than isolators.
Chassis damping
The carbon-fiber monocoque itself has some inherent damping characteristics. Teams can adjust:
- layup direction
- laminate thickness
- mounting inserts
to influence vibration transmission.
Man, thanks! post like this are what move the conversation forward instead of just pointing fingers.
From what i have read it seems that they are confident the source of the vibrations is the ICE (i mean its still a large area of investigation), i would then imagine that the provisonary fixes are the interface materials between chasis and engine mounts etc, then some counter weights in areas of the mount links (adding weight).
I do not think the updates are going to be only engine parts, i do believe they are going to change the engine bay sorrounding materials to change their flexing characteristics, apart from that i'm not sure what can be done there.
I would like to think honda has balanced the crank and camshafts as best they could, and it would be a massive miskate not to take than into account, what does that leave us? firing order? diffent or greater piston speeds? i remember the Yamaha MotoGP engine to have a different firing order.
Vibrations are terribly complex and they add up i know everybody is mad and don't understand how could Honda possibly missed this, but reallity is that until the engine and the chassis are fulli assembled there is no way to know how both will interact with each other in this regard.
