Abstract
When designing the structures of modern hydroelastic systems in power engineering, namely heat exchangers for various purposes, effective frequency tuning should be purposefully carried out to prevent intense vibration of individual elements. To do this, it is necessary, in accordance with the specified resource requirements, to provide reasonably defined ratios of various values of the natural oscillation frequencies of the structural elements and the characteristic nearest excitation frequencies in the flow. The optimal choice of the values of the frequency tuning coefficients is realized taking into account the characteristic known factors of hydroelastic systems, such as the effects of attached masses and the significant influence of damping on the intensity of vibrations of the structure in the fluid flow. The article provides a description and a general plan for solving the set complex problem based on the results of numerical and experimental studies known in this direction.
