摘要：Aiming at the problems of large free travel, heavy steering and slow response of the existing mechanical steering system of electric tractor, a steer-by-wire system directly driven by linear actuator was proposed and studied in this paper. The steering process of steer-by-wire system was analysed theoretically, and the simulation model was established based on MATLAB/Simulink. The following response and step response of steering system were simulated and tested. In order to verify the steering performance of the steer-by-wire system in electric tractor, the in-situ steering test and road-drive test were carried out on the modified prototype. The results showed that the designed steer-by-wire system could meet the requirements of low-speed driving of electric tractors, with fast response, stable steering and good overall tracking performance.
