Abstract:

The dynamic vibration absorbers have been applied to attenuate the rotor unbalance and torsional vibrations. The major purpose of this paper is to research the elimination of the fluid-induced vibration in the rotor/seal system using the absorber. The simplified rotor model with the absorber is established, and the Muszynska fluid force model is employed for the nonlinear seal force. The numerical method is used for the solutions of the nonlinear differential equations. The nonlinear responses of the rotor/seal system without and with the absorber are obtained, and then the rotating speed rang

Abstract The dynamics of a nonlinear passive vibration absorber conceived to mitigate vibrations of a nonlinear host structure is considered in this paper. The system under study is composed of a primary system, consisting of an undamped nonlinear oscillator of Duffing type, and a nonlinear dynamic vibration absorber, denominated nonlinear tuned vibration absorber (NLTVA). The NLTVA consists of a small mass, attached to the host structure through a linear damper, a linear and a cubic spring.

Linear vibration absorbers can only capture certain discrete frequencies. Therefore the useof nonlinear vibration absorbers which can capture a whole range of frequencies is investigated asan alternative. Such a nonlinear vibration absorber has some special characteristics. For examplethere is a certain frequency-energy dependence. To investigate nonlinear dynamical systems thereis a need for new methods. The harmonic balance method is such a method and is discussed. Theidea is to substitute a Fourier series expansion of the solution variables into the system equations and’balance’ them. Furth

Abstract:

A vibration control method is proposed to suppress nonlinear large vibration of the flexible robotic arm undergoing rigid motion. The method takes advantage of modal interaction and is implemented based on internal resonance. To attenuate vibration of the flexible arm, another vibrating system, consisting of a rigid link, a flexible joint and a damper, is introduced as a vibration absorber. Perturbation technique is used to study the transient response of the nonlinear equations of motion. Numerical simulation results preliminarily verify that the proposed control strategy is able to effective

Abstract:

Modal coupling is an important characteristic of most nonlinear dynamic systems. Although the existence of modal coupling can make the dynamic responses of a system quite complicated, it can be utilized to provide potential solutions to regulate nonlinear vibration. In this paper, the mechanism of modal coupling is used as a means to suppress vibration of a flexible arm undergoing joint motion. A secondary oscillatory system is attached to the flexible arm to generate appropriate modal coupling. Via this nonlinear coupling, internal resonance can be successfully induced and used to transfer vi

Abstract:

To suppress the vibration of a rotor system, a vibration absorber combining negative stiffness with positive stiffness together is proposed in this paper. Firstly, the negative stiffness producing mechanism using ring type permanent magnets is presented and the characteristics of the negative stiffness are analyzed. Then, the structure of the absorber is proposed; the principles and nonlinear dynamic characteristics of the absorber-rotor system are studied numerically. Finally, experiments are carried out to verify the numerical conclusions. The results show that the proposed vibration absorbe

Abstract:

The dynamic response of structures subjected to high-amplitude vibration is often dangerous and undesirable. Dynamic vibration absorbers (DVA) have received special attention in recent years due to vibration attenuation offered by them. Thus, the present study analyzes the nonlinear dynamics of a system with a dynamic vibration absorber (DVA) using a shape memory material (SMM) whose characteristics are highly dependent upon temperature. The restoring force of the oscillator is provided by a shape-memory device (SMD) described by a thermomechanical model capable to describe the hysteretic beha

Abstract:

A two-degree-of-freedom model of a nonlinear vibration absorber is considered in this paper. Both the global bifurcations and chaotic dynamics of the nonlinear vibration absorber are investigated. The nonlinear equations of motion of this model are derived. The method of multiple scales is used to find the averaged equations. Based on the averaged equations, the theory of normal form is used to obtain the explicit expressions of normal form associated with a double zero and a pair of pure imaginary eigenvalues by Maple software program. The fast and slow modes may simultaneously exist in the a

Abstract:

This paper presents the optimal design of a passive autoparametric cantilever beam vibration absorber for a linear mass-spring-damper system subject to harmonic external force. The design of the autoparametric vibration absorber is obtained by using an approximation of the nonlinear frequency response function, computed via the multiple scales method. Based on the solution given by the perturbation method mentioned above, a static optimization problem is formulated in order to determine the optimum parameters (mass and length) of the nonlinear absorber which minimizes the steady state amplitud
