By solving the governing equation for the boundary conditions along the surface, expressions in simple closed forms are developed for the dynamic response analysis of massless rigid foundation that rests on the ground surface. Applying Galerkins procedure for weighted residual, this equation leads to governing equation only at the ground surface behavior can be computed even further by simplified model. Nogami, The ground deformation under the wheel acts like nonlinear spring during the vehicle movement and influences the vehicle vibration.
During the longitudinal travel of the vehicle, arbitrary ground profile is an input of vertical excitation to the vehicle while the level of excitation varies depending on the soil deformability. Applying Galerkins procedure for weighted residual, this equation leads to governing equation only at the ground surface. The equation indicates that the ground surface behavior can be computed even further by simplified model.
Despite their significant simplicity, the developed expressions compute the values very close to those computed by far more complex rigorous solutions.
