| Abstract: | This paper build up 1/4 three DOF vehicle ride model which based on Matlab/Simulink application environment to simulink the vehicle running smooth of random road input. The certain vehicle is sorted by using sensitivity analysis theory to analysis the impact of the spring rate of the suspension, the vertical stiffness of rubber component of suspension, the stiffness of seat and tire on the vertical accelerate root mean square values. According to the simulation result to experiment optimization the rubber component of suspension system .The results of simulation and experiment are verify that changing rubber components stiffness can improve the efficiency of comfort ability. |
