Adjustable Valve Semi Active Suspension System for Passenger Car

The suspension of the car plays a very important role in the safety and the comfort of the vehicle and for absorbing the shock waves and give comfort for the driver and passenger. This paper improves the performance of automobile suspension system, by developing electronically adjustable semi active...
