I think that you also should take into account the difference in speed between the wheel and the ground. What I do in my simulation is the following: * Find Maximum Engine Torque based on the current engines torque curve and current rpm. * Find Actual Engine Torque = Multiply Maxumum Engine...

I found the error! :) The velocity of the second gear is \Delta\omega_{1}\frac{r_{1}}{r_{2}} and the torque needed to rotate it is \tau \frac{r_{1}}{r_{2}} which means that the formula should be: (\tau_{1}+\tau_{2}\frac{r_{1}}{r_{2}})\Delta t =...

Since I did not get any answers, I will change this into a simpler example: You have two gears (not welded double gears as in the first example, just two simple gears). The gears are connected to each other using a weightless chain belt. Each of the two gears have the following quantities...

I'm working on an offroad game and in that case, you also must take into account how much gravel your wheels push around, but maybe, that can be added afterwards, not affecting tire friction(?)... B.t.w., thank you Jeff for point out an excellent thread and PDF document. I have read the thread...

There is no one formula that perfectly describes this, since tire dynamics is a very complex and non-exact issue. The "Magic Formulae" by Mr. Pacejka might be the closest approximation that can be used for a lot of different tires. Some of the things that affect the outcome are: * Road...

I am working on a vehicle based computer game. The focus right now is to get the internal physics of each drive line component as physically correct as possible. Since a few weeks, I am stuck with a problem that I cannot get past by myself. I have narrowed it down to a specific issue. It should...
