In common with carriages and railway locomotives, most early motor vehicles used leaf springs. One of the features of these springs was that the friction between the leaves offered a degree of damping, and in a 1912 review of vehicle suspension, the lack of this characteristic in helical springs was the reason it was "impossible" to use them as main springs. However the amount of damping provided by leaf spring friction was limited and variable according to the conditions of t… Webcharacteristics of the components (springs and dampers) are fixed.

WebSystem is critically damped when the damping ratio prevents overshoot . Passenger cars usually have an effective mean damping ratio around 0.3. This value gives less vehicle control but bigger vehicle comfort. Racing cars can have a damping ratio approaching 1.0. theoretical enthalpy
