A method for analytical and experimental determination of vertical tire stiffness and tire damping for a heavy dump truck is considered. Input data are experimental measurements of free vibrations of the heavy dump truck after crossing a single asperity. The method is based on the procedure for identifying the vertical tire stiffness and tire damping by comparing the experimental and analytical data obtained from the model. The results of approbation of the proposed method are given by example of the specific dump truck model by using Matlab/Simulink Software.
