Purpose: The main aim of this paper is improved dynamic vibration absorbers design with taking into accout complex rotating machines dynamic. Design/methodology/approach: The numerical schemes row is considered for the complex vibroexitated constructions. Methods of decomposition and the numerical schemes synthesis are considered on the basis of new methods of modal synthesis. Findings: Development of mathematical models of complicated machines and buildings in view of their interaction with system of dynamic vibration absorbers. Dynamic vibration absorbers - complicated rotating machines system design optimized on vibro- absorption properties. Research limitations/implications: The research must be done for non-linear rotor dynamics. Practical implications: The absorbers designed in accordance with this paper can be applied not only to electric machines or aeronautic structures, but to any other type of vibro-exitated structure, such as cars, chisel installation, optical, magneto-optical disks, washing machine, refrigerator, vacuum cleaner, etc. Originality/value: The paper has novelty both in theoretical, and in practical aspect. In order that optimal parameters of DVA be determinate the complete modeling of dynamics of rotating machine should be made. Traditional design methodology, based on discontinuous models of structures and machines are not effective for high frequency vibration.
