For the second, where the frequency of the applied torque is approximately equal to the structural frequency, it is suggested that the response is intermittently chaotic.
The instability can be suppressed or avoided by operating at small amplitude and low frequency of the transmitted torque fluctuation, and by operating in the weakly coupled torque/speed regime of the prime-movers.
This system is composed of a pair of absorber masses riding on epicycloidal paths that are tuned to one-half order relative to the frequency of the applied torque.
Finally, we investigate the dependence of chaotic dynamics on quantities such as body shape, degree of damping, and frequency of the perturbing torques.
Synchrophasor measurements are widely used for various monitoring, assessment and control applications such as state estimation [5], control of frequency fluctuation [6], torque angle control of rotor [7] etc.
In this article, a feasibility study of controlling the low frequency torque response of a disc brake system with modulated actuation pressure (in the open loop mode) is conducted.
At 2, 4, and 6 Nm of torque, tones with increasingly higher frequencies played through the speakers as a guide for the tester.
This filter was found not to affect the course of torque development; it only removed high-frequency noise from the signal.
Numerical results are presented to illustrate the influence of pile flexibility, geometrical properties of pile saturated soil system and frequency of excitation on the pile's torque, torsional angle and coupled impedances.
In this paper, we compute the frequency of the oscillations of the power, torque and vibrations due to voltage unbalance and harmonics and we present laboratory results to verify the calculations.
