Sentence examples for unstable frequency from inspiring English sources

On the other hand, selecting a large inertial constant resulted in a controlled frequency deviation, although the unstable frequency of the power grid continued for a long time.

In the event that the nozzle lip axial ofiset is very large, coherent oscillations still persist, but in a different mode; the frequency is much higher, dictated by the most unstable frequency of the wall jet that forms between the nozzle lips.

Some unstable frequencies fall in the range 60 1200 Hz, which correspond to frequencies of rail corrugation.

This method can compute nonlinear periodic or pseudo-periodic responses depending on the number of unstable frequencies.

The aim of this paper is to improve the correlation between the experimental and the numerical prediction of unstable frequencies for automotive brake systems considering uncertainty.

The unstable mode frequency, growth rate and shape are in agreement with analytical results.

a Unstable vibration frequency f R = 331.44 Hz and corresponding effective damping ratio ξ = −0.001.

A novel feature was the non-vanishing real part of the unstable mode frequency due to the influence of diamagnetic drift.

The finding that the diamagnetic drift effects cause the real part of the unstable mode frequency confirms an earlier result by Miura et al. (1989), although for different physical reasons.

The unstable modes frequencies, amplitudes and shapes are accurately predicted.

When the friction coefficient becomes high enough, the resultant vibration becomes unstable as frequencies of two conjugate pairs of complex eigenvalues (poles) coalesce (when viscous damping is low).
