This is a very interesting point and it agrees with something I've been thinking for a while now.atanatizante wrote: ↑01 Apr 2022, 07:34From the above video Peter Wright says porpoising also induce bodywork oscillating adding maybe to the car/ICE frecvency (resonance?) that can lead to break the structures...
Thus all 4 customer PU teams which also have porpoising had to run in lower ICE modes just to diminish the bodywork resonance effect. That's why W13 and these cars are clipping sooner on the straights just to compensate with more harvesting and deployment...
In addition, for raising the ride hight to diminish the porpoiseing they need to compensate the downforce loss with both bringing a barn door rear wing and also with higher levels of AoA. It'll be useful to demonstrate this theory by showing some comparison between the rear wing levels of these 5 customer teams and the rest of the grid...
I didn't know about this possible resonance effect but when trying to understand how all Mercedes powered cars were seemingly more affected by porpoising I was thinking that the mass distribution of the power unit and its ancillaries (being similar among them all) could have an effect.
Maybe not the mass itself, but the geometry, materials and linkage between the PU and the chassis somehow contribute to a resonating frequency which is more aligned with the frequency created by this heave/pitch movement created by the downforce.
