| Abstract: | Vehicle handling stability is important, but is difficult to be realized for an auto engineer. We developed a handling stability model of two-axis vehicle based on its dynamics, in which the factors of redistribution of left and right tires' loads when rolling and nonlinear side forces were taken into account. Then the simulation was performed by using this model. The influences of many parameters and tilting of body on automobile handling stability were analyzed. The simulation results coincided with these from the experiments. Which indicated that the model was a precise and useful one for vehicle handling stability design. |
