I have been working on the steering system of our car for quite some time and we are very close to design completion.... We have calculated the steering ratio and rack speeds etc. which come out to be around 6 and 65mm/rev respectively. But, all the calculations have been done using front view trig.
While trying to verify my calculation results through the C-factor formula given in Milliken i.e. Steer Ratio = (arcsin(C-factor/steer arm length))/(360) i am stuck because I just can't seem to understand why the (c-factor/steer arm length) term is coming out to be greater than 1 (Our c-factor is 2.6667in/rev and our steering arm length is 2.36 in) ... Because of this it has been impossible for me to check if my earlier calculations are alright or not.
So, can you guys please guide me and try and point out what and where the error is.
