Purpose: The work presents methods of reducing vibration with the use of passive and active elements as well as reveals the results of implementation of active reduction of vibration applying mechanical elements in the form of kinematic excitation. Design/methodology/approach: The publication also includes structural and parametric synthesis understood as designing of mechanical systems with a desired frequency spectrum and presents analysis of obtained systems in order to verify if the latter meet related requirements. Findings: The research reveals that the application of kinematic excitation as the implementation of active reduction of vibration does not satisfy expectations as obtained models are characterised by frequency spectrum different to the desired one. Research limitations/implications: The research relates only to discrete vibratory systems, in which the reduction is carried out by means of mechanical elements. It is advisable to apply another type of elements e.g. electric ones. Practical implications: The results represented this work extend the tasks of synthesis to other spheres of science e.g. electric systems. The practical realization of the reverse task of dynamics introduced in this work can find uses in designing of machines with active and passive elements with the required frequency spectrum. Originality/value: Owing to the presented approach i.e. a non-classical synthetic method applied in designing mechanical systems, one (as early as at the design and construction stage) may verify future systems.
