Owing to the complexity of factors influencing controllability and stability of tractor-semitrailers, the simulation models of truck combinations are established with TruckSim. Based on a single lane-change test and orthogonal experimental design, the influence of main factors on vehicle safety is simulated. These factors are ranked according to their significance. At the same time, the relationship between the magnitude of factors and evaluation indexes is also investigated. Through selecting sets of appropriate factors and levels, parametric optimization is performed. Match analysis results show that suspension stiffness, wheelbase of tractor, center-of-gravity (CG) height of pay mass, CG height of tractor and distance between CG of semitrailer sprung mass (unloaded) and coupling pin have a remarkable influence on stability. The results and methods may provide references for research on tractor-semitrailers stability design and parameters match in safety considerations.
