| Abstract: | The paper analyses the theoretical basis of setting up dynamic model of mechanisms vibrations. According to the equivalent principle of the energy, the equivalent mass and stiffness of dynamic models of machine components are calculated. The formulas of equivalent mass and stiffness of the spatial cam shaft of three-degree-of-freedom are given. The errors of the relative reference books are revised. |
