Abstract
Vehicle dynamics and road dynamics are two separate subjects. In vehicle dynamics, road surface roughness is generally regarded as random excitation to the vehicle, while at the same time handling stability, ride comfort, and vehicle safety are all investigated. In road dynamics, the vehicle is generally regarded as a moving load acting on the pavement, while at the same time the response and lifetime of the pavement and foundation are all studied. This book suggests a new research concept to couple the vehicle and the road together with a three dimensional (3D) tire model. The dynamics of the vehicle, road, and the vehicle–road coupled system were investigated by a theoretical analysis, numerical simulations, and field tests. Chap 1 gives the state of research in vehicle dynamics, road dynamics and tire dynamics, and proposes the research scheme of vehicle-road coupled system dynamics. In Chap. 2, the lumped parameter models of two-axle and three-axle vehicle systems are established and the dynamic responses are analyzed. In Chap. 3, the nonlinear virtual prototype model of a heavy vehicle is set up, and an orthogonal optimizatio
