Ride Basically, suspensions are employed to deal with hump in road surface, in other words, enhancing ride comfort. When a car rides over a hump, the springs are compressed, store the energy thus provide shock absorption. The energy will be released quickly when the springs bounce back. Dampers are employed to smooth and slow down the bounce motion, this is called "Damping". Without dampers, the car will bounce up and down severely and quickly, this is perceived as uncomfortable. Study found that ride is perceived as comfortable by human when the bouncing frequency is 1 to 1.5 Hz. If it expeeds 2 Hz, most people feel the ride harsh. Therefore ride quality is mostly controlled by the selection of suitable springs and dampers. Handling In order to achieve ride comfort, we create suspensions and let the wheels movable with respect to the car body. Inevitably, this create many many problems in handling. When the car is turning quickly into a bend, centrifug...
