Purpose: The main purpose of this work is the introduction the algorithm of a analysis and synthesis of mechanical systems. The systems containing passive and active elements reducing of vibrations. In result of conducted synthesis was received structures and parameters of a discrete model meeting the defined requirements concerning the dynamic features of the system, in particular, the frequency spectrum. Design/methodology/approach: In this paper was used a non-classical method of polar graphs and their relationship with algebra of structural numbers. The use of such a method enables the analysis and synthesis of mechanical systems irrespective of the type and number of the elements of such a system. Findings: Presented approach simplifies the process of selecting the dynamical parameters of systems in view of their dynamical characteristics. The application of active elements to eliminate vibration enables overcoming limitations which occur if passive elements are used. Research limitations/implications: The scope of discussion is analysis and synthesis of passive and active mechanical systems, but for this type of systems, such approach is sufficient. Practical implications: The practical realization of the analysis and synthesis introduced in this work can find uses in designing of machines with active and passive elements with the required frequency spectrum. Originality/value: Thank to the approach, introduced in this work, can be conducted as early as during the designing of future functions of the system as well as during the construction of the system. Using method and obtained results can be value for designers of mechanical systems.
