Road Roughness, Evolution Random Response and Ride Comfort Based on Vehicle Vertical Dynamic

There are many kinds of vibration excitation sources for vehicles, such as inertia force during driving (centrifugal force during turning, inertia force during braking, etc.), aerodynamic force and excitation of uneven road surface. This chapter mainly introduces the random vibration caused by uneven excitation of road surface, because it is a kind of vibration that occurs a lot and often. The research on such problems originated in the 1960s.
