Obviously, if the team has solutions prepared for Suzuka, there will be changes to both the chassis and the engine. Thinking that only Honda will bring the solutions is ridiculous. Both sides will make changes because the fault lies with both. It's just that AM will never admit it.
What is it in the chassis that could cause or atleast amplify these vibrations caused by the engine? Purely technically speaking. I assume you have something in mind as i understand your wording as super confident.
The chassis is built of very rigid carbon fiber laminates; such a structure has less ability to dampen vibrations than a more flexible structure; there is the possibility of harmonic vibration at some natural frequency in the structure from engine vibrations at certain rpm. The chassis has to be rigid for suspension control so that it doesn't act as a spring, altering suspension action. Think of a wineglass and how it can be made to vibrate by rubbing its rim vs a plastic drinking cup and how it will simply do nothing. The motor, which acts as a chassis member and carries suspension loads, is rigidly mounted to the monocoque and engine vibrations can be carried into the chassis.

I think I have the same understanding of the underlying physics. Im referring to the explanation of the chassis somehow being the reason for the extent of vibrations getting transmitted, when this is inherently unavoidable by nature, considering the structure/behaviour of Carbon Fibre, which is why i dont really understand in what sense AM's chassis is supposed to be different to the other teams in this regard. It simply resonates what it gets fed by the engine...?
I lack the technical nuance around the connection of engine and monocoque to properly judge, but this seems like bs to me.

I wrote earlier today that you dampen the vibrations from several places. It's not about creating the vibrations from tge chassis but helping to dampening them from the chassis.
Saw your post, can you provide some sources/literature so that we can read up on this? This would mean that the solution would be as simple as adding more cushion, which i dont believe is the case.

Someone really believes Honda will be solve the vibrations in Japan? Honestly, for me, nothing will be change. I don't know anything about engines, but given the problems we've seen and their proportion, it doesn't seem like they'll be fixed even next year.
I also do not see them being fixed without an engine upgrade. Japan should be more of the same.
Why wouldn't they upgrade the engine? It's what they need to do.
They could and I don't know if things have changed since but going in Australia Honda was saying the problem isn't with the homologated parts.

I don't have any specific references. Just different sources I read up on. I'm in no way an expert. I don't think it's simple. I think it's more like a flute, covering or uncovering a hole(s) changes the vibrations/sound.

The chassis structure is not a simple layup of carbon fiber, it's a sandwich structure of carbon with a nomex honeycomb core that varies with stress requirements. There are many types of carbon prepreg with different load characteristics and weave patterns, as well as various fabric orientations during layup depending on design loads. For example, unidirectional fabric is used where loads need to be directed; there will be different construction where suspension loads are taken out, etc. Every chassis will be different and will have different characteristics and thus different reactions/harmonics to vibration. It's not 'bs', it's engineering.

Keeping in the mind that they are the guys doing this job, I think different PU structure of honda, maybe mounting points needed be different from more conservative ones. And going to the different way brings more room for unexpected issues to solve.

its too bad that they cant just slap a mercedes power unit into the AM chassis and see if newey truely did build a harmonic tuning fork of a chassis like people in here claim. seems pretty unlikely to me. especially given hondas history of vibrations tearing things up in the past, and somehow not being picked up on their test benches in sakura.

They run it already at 100%. Have you learned nothing from 2015? This is it.
That's not true. There is no reason for them to run the PU at 100% when they have major reliability issues caused by vibrations



On the good news side? Only 1 race between now and May first!!! That's gonna feel like morphine. Whole month and a half...the whole off season!
did they ever say whether the cancellation of 2 races would delay ADUO? i thought that the rules stated "6 races" and not a specific date. it seems like it would be better for them to do the first allowances at the time that the 6th race would have occured since it was based off of a 24 race season, but i doubt if they even thought of races being cancelled when making the rules
