Numerical Investigation of Continuous Damping of The Semi-Active Suspension System for Passenger Car

The suspension of the car is considered an important element in the vehicle. The primary function of the suspension system is to isolate the vehicle structure from shocks and vibration due to irregularities of the road surface. There are two main objectives need to be satisfied which are: ride comfo...
