Mechanical Subsystem as Implementation of Active Reduction of Vibration

Abstract

The main objective of this work is to present a reverse task of the dynamics of discrete vibratory mechanical systems. This task is reverse to analysis and is called structural and parametric synthesis. As a result of performing the synthesis one obtains a structure and values of individual parameters of the system of required properties. Such properties refer to the determination of individual frequencies of the system vibration. Synthesis is divided into two stages. The first stage consists in definition of the structure as well as the values of parameters of a passive system without vibration reduction. In the second phase, one selects a method of vibration reduction as well as system structure and parameters with vibration-reducing elements. In case of already-existing systems, the first stage consists in the identification of the system and its analysis. There are no changes in the second stage (Figure 1) [. Another objective of this work is to use mechanical elements in the form of kinematic excitations as the implementation of active reduction of vibration as well as to check the influence of this subsystem on the basic system. The application of the synthesis presented in this work enables the correction of the already-existing machines and devices as well as the modification of newly-created systems with the view of their future functioning.
