The model problem concerning numerical investigation of the forced vibration of the tube spiral with internal flows of the non-homogeneous liquid is set-up. Numerical designing of spiral tube rods dynamics is carried out. It is established that stable and unstable regimes of the elastic system motion can be disturbed under the action of inertial forces of internal flow of the non-homogeneous liquid with discontinuous inertial characteristics.
