Research on damping force regulation of magneto-rheological damper based on vehicle suspension

According to the magneto-rheological damping control method,the damping force regulation of magneto-rheological damper for vehicle suspension has been developed.The regulation characteristics of viscous damping force and coulomb damping force in magneto-rheological damper of automobile passive suspension and semi-active suspension have been analyzed,in which the input is Gaussian white noise of pavement.The optimal control method of magneto-rheological damper in semi-active suspension has been discussed.Then,the relation between the damping force control current of magneto-rheological damper in semi-active suspension system and the pavement incentive has been obtained based on the optimal control method by computer simulation.
