Project summary: The suspension system plays an important role in ride comfort and handling characteristics of an automobile. The optimum value of damping ratios required for ride comfort and handling of vehicles are very different and in general a compromise is reached in designing a vehicle’s suspension system. The suspension system designed by assuming a comprised value of damping ratio may have many shortcomings in ride comfort, ride handling and stability. 

Thus, frequency-dependent suspension drives may help a great deal in overcoming these difficulties. The adaptable nature of the suspension system to the desired characteristics makes the drive safer and smoother. The different kinds of semi-active technologies that exist currently are variable stiffness systems, variable orifice dampers, magneto-rheological and electro-rheological dampers, mechanically controlled valves etc. A variable orifice damper doesn’t have settling or in-use thickening limitations, perhaps the main reason to be used for 
seismic structures and also offer a great amount of controllability since the valve is electrically controlled. When a current input is provided, the electromagnetic field displaces the armature and in the process controls the orifice opening. The variable current supplied controls the level of opening of the orifice and thereby, control the flow of hydraulic oil providing variable damping to the system.
