The article presents the reasoning of the choice of the method and developed generalized mathematical model which describes the stationary spatial vibrations of a dynamic system of mobile wheeled vehicle that includes 12 solids, joined with 32 linear elastic – dissipative links which have 4 inputs and 20 degrees of freedom, and considers the possibility of installation continual type suspension. Algorithms of calculation of a vibration level on operator’s seat and loads of vehicle’s parts for various variants of excitation correlations on inputs of its system are presented in the article.
