| Abstract: | Research on the automotive rack-and-pinion hydraulic-assistant power steering system, suppose that the driver holds tightly on the steering wheel, regard the deflection angle emerged by the shock load on the front wheels as the input, and the outputs are： oil pressure of the left and right chambers of the driving chamber of the steering equipment, conversion valve input oil pressure, conversion valve torque .Study the oil pressure change and the road feed-back. Make the mathematic model, Matlab/Simulink simulation model, so as to analyze and research. |
