This research aims to evaluate the dynamic response of a plate on an orthotropic layered foundation under moving loads.
Established a three-dimensional coupled model using elastodynamic theory and Kirchhoff thin-plate theory.
Derived governing equations via double Fourier transforms and matrix analysis.
Conducted finite element simulations using ABAQUS to study effects of various parameters on dynamic response.
Layering of the foundation significantly influences plate deflection, with anisotropic conditions from the first soil layer having a pronounced effect.
Higher load speeds result in increased peak deflection, while higher load frequencies lead to decreased peak deflection.
Optimization of plate parameters effectively reduces deformation, and higher elastic modulus or thickness corresponds to decreased deflection amplitude.
