| Abstract: | The paper establishes the two degrees of freedom model,analyzes the stresses,introduces the appropriate differential equations of vehicle motion,and uses the Laplace transform to establish the transfer function of angle input motion and force input motion.Then,through MATLAB software programming,it solves the characteristic parameters of the two degrees of freedom vehicle model under the situation of the angle input and the power input,draws the curve of the characteristic parameters with the speed change,analyzes the trends,and makes a comparative analysis of response quality of vehicle handling stability with different inputs. |
