Abstract
In order to establish and solve vehicle-bridge interaction matrix equations more easily and able to be applied to any vehicle-bridge interaction problems, a procedure has been programmed based on the ANSYS and MATLAB. Its feasibility and accuracy has been verified via comparing the results of a simple example with another verified procedure programed in the same method based on MATLAB. A study of contrasting moving load model and moving sprung mass model has been done with the former procedure. It indicates that the inertia force of the mass has a low effect on the dynamic response of vehicle and bridge when the vertical roughness of the bridge and damping effect are ignored.
