I gave you the formulas and you couldn't do the math. If you can remember back that far I told you you need to it in 3D at the tire patch using the static coefficient of friction. And I also said not to use MathLab. You would then need to do it for the dynamic case and move on from there.
If you did that you would see how much better IFS is but you cant do it so you wont know.
Your expiation was below what a first semester mechanical engineer would need to be able to do in a Statics class in order to pass.
I can spot a pseudo-intellectuals craving attention and spouting nonsense along way away.
You gave me the formulas? That's funny. At least you have that going for you.
I'm not sure why you'd use matlab - I assume that's what you mean. The basic principles of the scenarios I've shown you are easy to do by hand. The empirical results are also pretty obvious. You can't model every rock, every dust particle, etc. because every condition you'll see is so random and variable. And there's no reason to do it. You won't learn anything we don't already know. Could you design a model and apply a Monte Carlo analysis to randomly generate trail conditions and take it to the extreme of including gravitational pull of the tennis racket 40 miles away? Sure. But it's pointless. You'd never find out more than what the basic calculations and experience both show. Solid axles distribute load better and follow terrain better as an inherent result of the design than IFS at low speeds in high articulation scenarios.
Even the Ford engineers explained that they knew IFS was a compromise and would not work as well in the rocks as a solid axle, but would be better on the road and going fast in the dirt. They went with a long travel, no sway bar, 3 link rear solid axle to compensate for the IFS's limited travel and flex. IFS is certainly the right choice for a 4Runner that's 90% road oriented and 10% dirt oriented. But there's also no question that a solid axle inherently has significant performance benefits in high articulation situations. Or I should say no question for anyone who's ever actually spent any time with it and would know from experience, or anyone who's compared the ground pressure distribution of the two suspension systems. But you're still here arguing that IFS would be better on the most difficult rock crawling type terrain. And that's factually wrong. I find it odd that we're arguing about it.
Presumably you also would prefer IRS too? Toyota does make a highlander. It's a great SUV. Might be right up your alley? IFS, IRS, lighter weight, more power. Presumably a fantastic rock crawler given that it has IRS as compared to the 4Runners crappy solid rear axle.
With respect to the 6AT:
What's odd is how you work so hard to keep avoiding talking about anything concrete. Why do you want to avoid the technical discussion? I'm trying to simplify as much as I possibly can. And I've give you the road map of where we're going. Play a long. It'll be fun.
Do you agree or not that two gears with different teeth counts in mesh result in different rotating speeds when in motion? Can we at least agree on that? If we start really simple we can walk through each step and by the end - we'll either agree or we'll find out what step of the analysis you don't agree with.
