Simuation Study of the Factors Effect on the Directional Controllability of Vehicles


This paper present the result of the work carried out the mathematical model of twodegree of freedom movement study the influence of cornering stiffness of tires, thedistance from the position of the center of gravity to front and rear axel and mass ofvehicles.Theoretical calculations have been carried out the vehicle have known mass and theposition of the center of gravity.Results show that for the state which is the front tires are bias ply tires and the rear tiresare radial ply tires is the best because the state gives under steer behavior. Also the statewill be the center of gravity nearest from the front axel gives the same behavior and alsoowing to the existence of center of gravity being nearest to the front axle.
