Vibration analysis of commercial vehicle cab suspension and DOE optimization

To study the vibration of cab suspension, a commercial vehicle cab suspension model which contains cab, seat, suspension parts and vibration exciter was built with ADAMS. The vibration equations of the cab suspension were analyzed. The model was simulated under the continuous accelerated excitation and the accuracy was testified. Design of Experiment method was used to optimize the model. By matching the stiffness and damping of the cab suspension, the vertical acceleration was reduced by 64%.The method was fit for optimizing the model.
