【Abstract】 The difference of the semi active suspension models based on the force control and that based on the damping rate control is analyzed in this paper. The non linearity of semi active suspension is elaborated. A model with two degrees of freedom of the semi active suspension based on damping rate is established and simulated by using fast frequency theory. The result shows that the semi active suspension has limited effect to improve vehicle performance.更多还原
