Hello! My college is currently going to participate in BAJA SAE for the first time ever. And from the video above I can see a lot of assumptions that we have to take. Can you please tell me how u reached those assumptions. I mean the stuff like wheelbase, track width, kingpin inclination, the angle for tru Ackermann etc. Another doubt was that I think the track width limit is 64in. Why go for a small track width of 54in.??
You need to assume that from the range of 38 degrees to a maximum of 45 degrees... Iterate the geometry keeping the values same and varying only the steering arm angle, you'll find the relation between the parameters and you'll be able to achieve an optimum value. The logic behind the steering arm angle is that the lines extending from the steering arm should meet nearest to the rear wheel center line
@@murtaz1406it is anti Ackerman geometry cause the steering arm is at a obtuse angle and you can check by giving turn angle to both wheels and see outside is turning more

Our collage is participating in SAE REEV
I got too many doubts in this geometry is there anyway to contact you?

how to get the steering arm angle?

This is anti Ackerman steering geometry
I'm pretty sure this is Ackerman geometry.
One mistake is that it is leading arm geometry rather than trailing arm.
