Electrical Elements in Reduction of Mechanical Vibrations

Abstract

This work presents methods of reduction of the vibration of mechanical systems by means of active elements as well as examples of implementation of active reduction of vibration by means of electrical elements [. 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. 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 [1-. This work presents the description of vibration reduction methods. The most popular methods are passive, active and semi-active. An important aspect of this work is the presentation of several possibilities of the physical implementation of active subsystems. In examples active subsystems consisted of the following electric elements is coil with a movable core. In this work is presents influence of electrical subsystem to basic mechanical system. Designer should analyse the resultant systems and investigate the interaction between the subsystems and the basic system [4-.

Method of calculating variable section shafts shear deformations

“…Control over rotating electrical machines dynamic state according to the engineering status is carried out by various engineering systems. Vibration diagnostics systems are most important among them [1][2][3][4][5][6]. The development of such systems is a difficult task, since should be determine the parameters that can estimate the machine state.…”

Backstepping integral control for hydraulic servo system based on LuGre friction model

“…A hydraulic shaking table is a typical hydraulic servo system with advantages such as a lower frequency limit and higher shaking force. They are widely used in civil engineering, transportation, environmental simulation, and other fields [1,2]. Compared to an electro-magnetic excitation shaker, the hydraulic shaking table has a stronger nonlinear characteristic.…”

Application of Electric Subsystem as Implementation of Reduction of Mechanical Vibrations

“…In examples, active subsystems include a coil with a movable core and piezoelectric elements. The synthesis presented in this work is non-classical approach to design of vibrating mechanical system with active reduction of vibrations [1][2][3][4][5]. As a result of the synthesis, one can obtain the structure and parameters of the system of required properties.…”
