Abstract

Through the establishment of dynamic model of tractor-semi-trailer, Laplacing transform them, finding the system transfer function; Changing in the use of tractor-semi- trailer and structural parameters, using of MATLAB programming for digital simulation, finding the root locus; Then according to the root locus changes in trends, to determine whether the system is stable and the size of the stability margin. The results showed that: Speed, tire cornering stiffness, the quality of tractor and trailer, trailer Centro -symmetric hinged points, the distance between the quality parameters such as vehicle handling and stability of the semi-trailer in different degree of influence of, selection of rational parameters can be manipulated to improve the stability of tractor-semi-trailer.
