The 5-DOF man-vehicle-road coupled vibration model was established by the relationship among three interactions of man-vehicle-road, and the vibration differential equation of the 5-DOF man-vehicle-road model was obtained by Newton’s method. The mathematical model was conversed into the derived simulation model based on MATLAB/SIMULINK software. The vibration characteristics of the 5-DOF couple model were analyzed by the excitations of ride speed and random road surface roughness time series after the corresponding parameters were set. We also gave the acceleration curves and its response characteristics of the bodywork and man-chair system. The study results have a guiding significance and reference value to analysis the vehicle ride comfort.
