Dynamics control of an autoparametric system with the spherical pendulum using mr damper

Sado D., Freundlich J.

Vibrations in Physical Systems

Vol. 29

art. no. 2018016

Dynamic properties of the three degrees of freedom autoparametric system with spherical pendulum including the magnetorheological (MR) damper are investigated. It was assumed that the spherical pendulum is suspended to the oscillator excited harmonically in the vertical direction. The influence of damping force described by Bingham’s model on the energy transfer can be modified by magnetic field. The equation of motion have been solved numerically. In this type system one mode of vibration may excite or damp another one, and for except different kinds of periodic vibrations there may also appear chaotic vibration. Results show that MR damper can be used to change the dynamic behavior of the autoparametric system with spherical pendulum giving semiactive control possibilities.

Vibration Control of Autoparametric System Using MR Dampers in the Pendula Joints

Sado D., Pietrzakowski M.

Machine Dynamics Research

2013

Vol. 37, No. 4

97-107

In this paper a three-degree of freedom autoparametric system with a double pendulum including the magnetorheological (MR) dampers in the pendula joints is investigated numerically. The system consists of the two coupled pendula hangs down from the oscillator. Near the resonance regions except multiperiodic and quasiperiodic vibration, also chaotic motion may appear. For characterising a chaotic response the bifurcation diagrams, Poincaré maps and maximal exponent of Lyapunov for different magnetorheological damping parameters are constructed. The influence of damping moment in the pendula joins (described by Bingham’s model) on the phenomenon of energy transfer can be modified by magnetic field. Results show that MR dampers can be used to change the dynamic behavior of the autoparametric system giving semiactive control possibilities.

Simulation examination of active and semiactive damping of structural vibrations

Tylikowski A.

357-362

The aim of the paper is to present a review of problems related to active and semiactive control of structural vibrations with special emphasis put on the role of simulation. Depending on criteria of interest the problems of smart (intelligent, adaptive) structures can be divided into different categories to include fundamental research on the one hand, and simulations of quite sophisticated systems on the other.
