ELIMINATING TRANSVERSE VIBRATIONS ON AN ELASTIC BEAM USING DAMPERS

Аннотация

This article examines the optimization of the parameters of an elastic beam with dynamic vibration dampers during transverse vibrations. Methods for damping transverse vibrations in the elastic beam under consideration were analytically found. In particular, the change in the optimal parameters of the system under consideration is analyzed depending on the mass ratio and changes in the installation locations of dynamic vibration dampers. The article discusses the optimization of the parameters of a system of elastic beams under stationary vibrations with two dynamic vibration dampers. The solution to the problem of transverse vibrations of a beam with two parallel installed dynamic vibration dampers is considered, using the method of series expansion in vibration modes. This method is more convenient for optimizing the parameters of dynamic vibration dampers for various types of beam vibrations with boundary conditions, when it is necessary to repeatedly calculate the amplitude-frequency characteristics of the system.
