Without skidding of the tires and also the Ackermann geometry is favored for the slow speed vehicle as the speed limit for the vehicle we are designing is 60 km. Now considering both the tires the steering angle has now to be calculated taking into account that both tires turn by a different amount. Ackerman steering design calculations.
Ackerman Steering Design Calculations, Then we can take Rx-LxRx to express ackerman as a percentage. Ackerman steering is normally computed using a Jeantaud diagram Charles Jeantaud in 1878 created a geometrical method to arrive at Ackerman steering where the equal length steerings arms are placed on a line connecting the wheel center and the center of the rear axle. To calculate the steering angles the block uses these equations. Here steering ratio shows the ratio of steering wheel rotation to the Ackerman angle rotation.

Design of Ackerman steering geometry By putting all these values we got R 3119m Steering Ratio. The angle between the tie rod and the steering arm are what decides Ackermann geometry. Although Ackerman can be achieved by having different steer arm lengths on each side I do not think this is optimum for cars running longer tracks. So Ratio Steering wheel rotation Ackerman Angle rotation 90.
To calculate the steering angles the block uses these equations.
