A REVIEW WORK ON SUSPENSION SYSTEMS MODELS, CONTROL STRATEGIES FOR SUSPENSION SYSTEM (original) (raw)

— Ride comfort and handling performance of vehicle is contributed by suspension system in vehicle dynamics. There are different aspects which describe vehicular dynamics and ride comfort and handling performance but suspension system majors. Passive suspension, semi active suspension and active suspension have greater performance, suspension performance is understood by quarter car model with two three degrees of freedom at each of wheels, half car model with four degrees of freedom viz, roll degree of freedom and pitch degree of freedom. And full car model with seven degrees of freedom four degrees at sprung masses and three degrees at sprung masses. Quarter car model is more researched since model is simple, as degrees of freedom increases complexity increases. After comparative comprehensive studies, it is deduced that electromagnetic active suspensions are the future trend of automotive suspensions due to simple structure, high-bandwidth, accurate and flexible force control, high ride quality, good handling performance, and energy regeneration.
