Calculating Maximum Steering Angle of a Car

[varunsangani]

sir,

how can we calculate maximum steering angle of a car. i have the following details:
turning radius = 4.6 mts
wheel base= 2360mm
track=1495mm
also can you please suggest the relation for steering angle and turning radius and what are the values necessary for calculation of steering angle .

Have you tried looking at any automotive engineering books?

Hi Varun,

You can use the quote feature by typing

and /quote (the last one should also be in [ ]'s). I would look at SAE publications, and probably Fundamentals of Vehicle Dynamics by Gillespie.

It also depends on what you mean by maximum steering angle, do you mean acutally how much the wheel rotates, or how much you turn as they are not the same thing.

At low speeds your max steering angle is simply determined by the geometry of your suspension and wheel/arches. ie you put the steering lock before the wheel rubs on anything.

At higher speeds, slip angle of the tyre is what controls the turn. It is related (but not linearly) to steering input.

As far as I remember this was convered in Ranger Mikes suspension class.
