OK. I agree about additionally showing forces and moments, but I think the resulting visual would have been much too dense. I'm far outside of this field and have no access to simulations nor sufficient curiosity to pay for the pertinent seat license(s) to achieve simulations.
About the slip...
Hi Cibachrome - All of that makes sense. My hypothetical axle is in static equilibrium after the steady state is attained, so the external moments and forces must sum to zero. The initiation of the transient state as I've described it could be created by having the vehicle's COM height go from...
Hmmm. Interesting and thank you once again, cibachrome. I think to make significant headway here we'd all need to be standing in front of a whiteboard. Trying to do this with words is very cumbersome...
Thanks, Cibachrome. I'm curious about the description of the transient to the steady-state transition where the steady state would have the tire contact patches spread a bit farther part from each other than would be the case if the tire normal loadings were equal. Is this valid?
Drats, I just wrote a long edit to that last post and it got lost...
Perhaps I should have said "inclined" instead of "banked." Again, assume the pavement is flat and has no curvature. R is infinite, if you will.
Also, I believe the velocity vectors do initially diverge due to unequal tire...
Thanks again. I think you're saying we get toe-in rather than toe-out. To make sure I communicated my second question clearly, please look at the diagram above. (For the time being, I'm only suggesting tire velocity vectors.) Was this your understanding as well? Vx and Vy are for the entire...
Thank you, Greg.
Then extending the question just a bit, if we have this straight-traveling solid axle where I will presume that all compliance resides only in the tires, then for a hypothetical car traveling along a flat surface banked left or right, and with a positive COG height, then with...
Greetings,
Interesting question: if we have a solid axle of a vehicle traveling in a straight line path, do the two tire velocity vectors always need to be parallel, i.e., do the tires have to have the same slip angle? (I'm imagining a vehicle traveling along a banked section of pavement, for...
Again, I need to emphasize that a shunt-action failure mode is only my speculation about how the system would react. My *guess* is that should the system fail, that it needs to function in a way that approximates a passive suspension system, where the shock absorbers, to first order, apply a...
I'd ask the engineers directly, as they're personal friends of mine, but the company is internally (let alone externally) extremely tight-lipped about development projects. Communication is strictly on a need-to-know basis; that's why I had to hazard a guess as to how the system would operate...
Concerning failure modes - first, the system in its current envisioned configuration, uses, or would use, torsion bars to provide the nominal spring force. Second, I'd imagine that should elctronic control of the corner motors fail, that they would operate default in shunt so as to provide...
