Abstract
The handling stability of three-axle vehicle with dual-front-axle-steering system was influenced by steering angle ratio of front axle to middle axle. A differential equation with tire magic formula was established to describe the plane motion with two degrees of freedom of three-axle vehicle with dual-front-axle-steering system. The vehicle steady and transient responses on steering wheel angle step input were numerically simulated. The influences of steering angle ratio of front axle to middle axle on steady and transient responses of several vehicles with different wheelbase and position of mass center were contrasted. The change rules of yaw angular velocity gain, reaction time and overshoot with steering angle ratio of front axle to middle axle were acquired. The results show that the handling stability can be improved by changing the steering angle ratio of front axle to middle axle according to vehicle design parameters.
