Abstract: Aiming at alleviate and avoid the injury caused by steering system to the driver when accident happened, and servo motor output torque shortage in the steerbywire system, this paper improves the steering system, cancels the mechanical connection between the steering device and the steering wheel, replaces servo motor drive mode of the steerbywire system by hydraulic device drivers, overcome the lacking of outputtorque of servo motor, and the large effect of response caused by steering working conditions, using AMESim to simulate and analysis the improvement of steering system, simulate the steering system response under the different inputexcitation the result shows that the improved steering system has a great instantaneity and following accuracy to signal, thus verified the feasibility of the improvement program.

 

Key words: steering system; flexible; simulation; AMESim
