Application of mechanical and electrical elements in reduction of vibration

Purpose: This work presents methods of reduction of the vibration of mechanical systems by means of passive and active elements as well as examples of implementation of active reduction of vibration by means of electrical elements and mechanical elements in the form of kinematic excitation. Design/methodology/approach: This work also describes a structural and parametric synthesis, which can be defined as the design of systems meeting specific requirements. These requirements refer to the frequency values of the systems’ vibration. Findings: The examples of implementation of active subsystems presented in this work point out to the fact that one can use mechanical elements as well as electrical elements to reduce mechanical vibration. By applying such elements it is possible to obtain mechanical energy necessary for the active reduction of vibration. Research limitations/implications: The deliberations presented in this paper are limited to the presentation of possible physical implementation of active elements by means of mechanical and electrical elements. In active subsystems one may also use elements from other environments. In the next phase one should analyse the resultant systems and investigate the interaction between the subsystems and the basic system. Practical implications: The results represented this work extend the tasks of synthesis to other spheres of science. 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: 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.
