Summary

 
Object and purpose of research. The object of the research is model tests of the submerged body motions near the free surface in test basin. The purpose of the study is to determine how the magnitude of the relative vertical shift of the submerged body depends on its speed.
Subject matter and methods.The material for research is the modeling technique, technology and the results of model experiments in the test basin. Numerical modeling was performed using the ANSYS software package.
Main results. Model tests and numerical experiments were carried out to determine the magnitude of the vertical displacement of the submerged body moving near the free surface and the forces acting on it.
Conclusion. The results obtained are useful for horizontal stabilization of submerged body moving near free surface at different speeds.
