The 1/4 vehicle model is used to simulate the vehicle system, the limited size Kirchhoff thin slab simulation road and the Kelvin viscoelastic foundation are used to simulate the roadbed, and the roadbed response system under static load is established. Based on the thin plate theory and the viscoelastic theory, the dynamic response analysis of the vehicle pavement subgrade system under static load is obtained by using the vibration theory. The influence of the four parameters of the foundation damping coefficient, the foundation reaction modulus, the pavement elastic modulus and the pavement thickness on the pavement displacement And stress response. The research results have important theoretical significance and engineering application value for the interaction mechanism between vehicle and pavement system.
