Purpose: The main aim of this paper is improved dynamic vibration impact and particle absorbers design with taking into account complex machines dynamic. Design/methodology/approach: The numerical schemes row is considered for the complex vibro-loaded constructions. Methods of decomposition and the numerical schemes synthesis on the basis of discrete-continuum modelling are considered. Findings: Development of mathematical models of complicated machines in view of their interaction with system of dynamic vibration absorbers. Dynamic vibration absorbers – complicated machines system design optimized on vibro- absorption properties. Research limitations/implications: The research must be done for non-linear machine 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-loaded structure, such as turbo machines, pumps, cars suspensions, 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 modelling 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. The one-digit values are established not only for the dynamic vibration absorber parameters, but also for mechanical of base structure in connection points of the dynamic vibration absorbers.
