| Abstract: | With the advent of increasingly prominent energy source crisis and the development of electronic products of automobile in 21st century, those electric power steering systems with the properties of energy-saving and packed structure suggest the direction of future designing.. Aiming at this practical request,the factors of effect on automotive steering torque are analyzed according to the steering torque that is got from the stress analyzing of the steering gear. Using least square fit,the analytic expression of the part of steering torque, which is related to centripetal acceleration, is gained in detail according to experimental curves. |
