Summary

 
Object and purpose of research. The object of the study is compact lamellar resonating vibration absorbers (RVA). The purpose of the study is to develop a method for calculation of the dynamic strength of RVA, designed to assess the possibility of their use in ship shafting systems.
Subject matter and methods. The initial data and material for the study were the design of a plate-shaped resonating vibration absorber and the amplitude value of the variable components of the forces accompanying the bending vibration of the shaft line. Simplified methods for calculating the dynamics and strength of plates during their deformation in the elastic region are applied.
Main results. Developed method for calculation of dynamic strength of RVA. Relations are obtained that make it possible to choose the geometric dimensions of the RVA that ensure its dynamic strength and vibration damping efficiency.
Conclusion. The possibility of ensuring the vibration resistance of the RVA designed to dampen the vibration of the shaft span is confirmed with the initial data accepted in the problem.
