The possibility of physical implementation of active vibration reduction

Abstract

Abstract This work presents non-classical method of design of mechanic systems with subsystem reducing vibrations. The purpose of this paper is also introduces synthesis of mechanic system with reducing vibrations understand as design of this type of systems. This work presents method of reduction unwanted vibration by using mechanical elements, electrical elements, magnetorheological damper ect. 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. The purpose of this paper is also introduces synthesis of mechanical system which is the reverse task of dynamics. The result of synthesis is obtaining system meeting the defined requirements. The system was consisted from mechanical elements and sub-system realized by many types of elements. This subsystem is an active or semiactive subsystem which enables overcoming limitations which occur if passive elements are used. The majority of vibration occurring in devices and machines is harmful and has a disadvantageous effect on their condition. Harmful impact of vibration is caused by the occurrence of increased stresses and the loss of energy, which results in faster wear machinery. Introduced in this work approach adopted makes it possible to undertake actions aiming at the elimination of phenomena resulting in the unwanted operation of machinery or generation of hazardous situations in the machinery environment. Thank to the approach, can be conducted as early as during the designing of future functions of the system as well as during the construction of the system.
