One way to design ackerman steering geometry is to use rack and pinion with tierods. When turning the inside tire travels a shorter radius than the outside tire and thus must have a greater steer angle to avoid tire scrub. The equations for the value of the wheel angles based on the rod lengths and initial angles are more complex calculations than first might appear. For instance, steering ratio is chosen for a pair of ackerman angles, which in turn, are governed by turning circle radius targets.

)/steering wheel diameter =(5253.5875*0.7)/200 =18.39. We consider inner turning radius is 2) outer wheel lock angle, now by correct steering geometry, By subtracting the reciprocal of the latter two equations, we arrive at the ackerman steering equation: Point b’s x coordinate = raa * cos(aa + sal) point b’s y coordinate = raa * sin (aa + sal) where :raa.

Ackerman steering geometry is most widely used today in commercial vehicle. If you are going to use it, high percentage ackerman is required because ackerman is slow to build eg 100% ackerman, 4 degrees of steer angle at the steering axis gives approx 1 degree (or 6mm) toe out overall. To achieve this with your with cad programme you will.
