Simuation study of the factors effect on the directional controllability of vehicles

Abstract EN

This paper present the result of the work carried out the mathematical model of two degree of freedom movement study the influence of cornering stiffness of tires, the distance from the position of the center of gravity to front and rear axel and mass of vehicles.

Theoretical calculations have been carried out the vehicle have known mass and the position of the center of gravity.

Results show that for the state which is the front tires are bias ply tires and the rear tires are radial ply tires is the best because the state gives under steer behavior.

Also the state will be the center of gravity nearest from the front axel gives the same behavior and also owing to the existence of center of gravity being nearest to the front axle.
