Random Vibration of a Nonlinear Autoparametric System
A noisy autoparametric system exhibiting 1:2 resonance is studied as a random perturbation of a fourdimensional Hamiltonian system. The problem involves three time scales. Nonstandard stochastic averaging technique is rigorously developed, application of which results in a lower-dimensional description of the system. Probability density of the limiting process is obtained using FEM methods. The...
متن کاملAutoparametric Vibrations of a Nonlinear System with Pendulum
Vibrations of a nonlinear oscillator with an attached pendulum, excited by movement of its point of suspension, have been analysed in the paper. The derived differential equations of motion show that the system is strongly nonlinear and the motions of both subsystems, the pendulum and the oscillator, are strongly coupled by inertial terms, leading to the so-called autoparametric vibrations. It ...
متن کاملdesign and performance evaluation of tuned vibration absorber for the vibration control of a centrifugal pump
with the prolonged use of domestic centrifugal pump, due to erosion, corrosion and an unbalance the sever vibration of the pump are resulted. an erratic sound coming out of pump makes the user uncomfortable. here, tuned vibration absorber (tva) is used as a vibration controlling device. it is designed to reduce the rms velocity below 20% of the circumferential speed, at which the impeller is ba...
متن کاملA Hybrid Control Approach for Vibration Reduction of a Tower with a Pendulum Absorber
The oscillations of tall slender towers under environmental loads are usually of large amplitude. In order to protect these structures, suitable absorbers can be installed to control or limit the amplitude of oscillation. In this paper, passive and hybrid control strategies are used to improve the dynamic response of a tall tower. A pendulum attached to the top of the tower is used as a vibrati...
متن کاملUsing Dynamic Vibration Absorber for Stabilization of a Double Pendulum Oscillations
In this paper a stability problem for double pendulum is discussed. A damping device of passive type is used to stabilize small free oscillations of perturbed system. The simplified approach is suggested to prove the asymptotic stability of equilibrium.
