Vibro forming process and three stages of process of concrete consolidation are considered. Principle of hydrovibrator functioning is described and differential equations of its motion are derived. The traditional methodic of investigation of dynamic systems is used. Firstly, differential equations of motion of hydro mechanical system are established and then they numerically are solved. A set of recommendations for the parameters of equipment are developed allowing to start geometry designing process. Necessity of developing of adequate dynamic model of molding object is discussed. More detail calculations are planned after developing of the 3D geometrical model and the model of technological load that will allow valuable optimization of equipment dynamics and development of final variant of the design documentation.
