speed car to be run on our local dry lake bed. I have been
researching for a while and thought this would be the best place to
ask my question.
I plan on designing my own steering servo, but I am not sure how to
calculate how much torque I will need.
The car will weigh approximately 50 lbs, with maybe 15 to 20 lbs on
the front wheels. Speeds may be around 120 to 130mph. The steering
will have very little travel, just enough to keep the car going
Is there a simple way to determine how much torque I will need to
easily turn the tires while stopped (which I imagine will not be very
much). But more importantly, is their a way to determine how much
torque I would need to keep the tires straight at high speeds. I am
worried about imperfections on the lake bed that my put a side force
on the tire.
I am an electrical engineer and have good machining skills, so all the
electronics and machining I have no problems with. It's the physics
knowledge I lack. Being a robotics group, I was hoping someone could
guide me in how to determine what I need.
