The combined system consists of shells, beams and massive elements connected within each other. The deformed state of each element is defined with the help of generalized coordinates which are determined through characteristic displacements. The main part of characteristic displacements are mode shapes of each substructures. On the base of the developed metodology the model problem was solved to confirm the efficiency of the technique. The numerical analysis establishes, that the input of contact interaction's force into the equations of vibro-impact systems motion allows the model the impact between bodies both at harmonic and at a random external load. This force is varied on the contact Hertz law. The law of the motion of the vibro-impact systems bodies along the all time axis including the impact period is received. There is spared the attention to the questions of the oscillations dampingefficiency.The methodics of flat-bending dynamic stability of elastic systems with combine resonance research was worked out.
