Stochastic resonance in a nonlinear mechanical vibration isolation system
This paper concerns the effect that a stochastic resonance can have on a vibration isolation system. Rather than reducing the transmitted force, it is shown that it is possible to significantly mask the component of the force transmitted though the isolator, when the system is excited harmonically. This can be achieved by adding a very low intensity of random noise to the harmonic excitation fo...
متن کاملCombination Resonance of Nonlinear Rotating Balanced Shafts Subjected to Periodic Axial Load
Dynamic behavior of a circular shaft with geometrical nonlinearity and constant spin, subjected to periodic axial load is investigated. The case of parametric combination resonance is studied. Extension of shaft center line is the source of nonlinearity. The shaft has gyroscopic effect and rotary inertia but shear deformation is neglected. The equations of motion are derived by extended Hamilto...
متن کاملKinematic Signature of a Rotating Bar near a Resonance
There have been several recent suggestions that the Milky Way has rotating bar-like features based on HI and star count data. In this paper, I show that such features cause distinctive stellar kinematic signatures near OLR and ILR. The effects of these resonances may be observable far from the peak density of the pattern and relatively nearby the solar position. The details of the kinematic sig...
متن کاملRandom 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 کاملSuppression of the primary resonance vibrations of a forced nonlinear system using a dynamic vibration absorber
In a single-degree-of-freedom weakly nonlinear oscillator subjected to periodic external excitation, a small-amplitude excitation may produce a relatively large-amplitude response under primary resonance conditions. Jump and hysteresis phenomena that result from saddle-node bifurcations may occur in the steady-state response of the forced nonlinear oscillator. A simple mass-spring-damper vibrat...
