I calculate the potential traction available at each tire and assume the amount of resistance that each tire is generating to counter the centrifugal load is proportional. This seems to work great in my simulations, up to the point where the inside tire reaches saturation.
Rotate the tires front to rear and see if you still get the same vibration. If not, then one (or both) of the front wheel/tires is out of balance and/or out of round.
Does anyone know of a "typo" and possible correction to the second one of the three transmissibility equations presented by Gillespie in his book (1992 Edition)? Two of the equations work wonderfully well for me and plot exactly as they should, but the very important "sprung mass response to...
It sounds like you are doing something a lot more complex than the way I would go about it. A typical plot of "sprung mass response to road input" transmissibility indicates that a damping ratio of anywhere from 0.2 to 0.4 is a good compromise. For the 1958 Jaguar XK150S the front suspension...
