Multitone signal harmonic balance method
Electronics Letters, 1999 A novel approach for generating the frequency/time conversion matrices of multitone signals is presented. Conversion matrices are normally used in the harmonic balance method to evaluate currents/voltages of nonlinear devices. The conditioning number of these matrices is a fundamental aspect and the proposed approach always generated matrices with the ...

On the Method of Harmonic Balance for Lumped-Element Transformer Models
International Journal of Circuit Theory and ApplicationsIncorporating the magnetic core material in a lumped-element transformer model generally results in a nonlinear network with hysteresis. This network can be solved subsequently in time domain, yielding the transient response of the transformer. To directly obtain the steady-state solution, the method of harmonic balance is superior to such a transient ...

Simulation of Payne Effect of Elastomeric Isolators with a Harmonic Balance Method
Shock and Vibration, 2012 In the presented work, a non linear effect of rubber referred as Fletcher-Gent effect or Payne effect is investigated. It leads to a change in the rubber dynamic modulus with vibration amplitudes and, consequently, modifies resonance frequencies of ...

Linearization of friction effects in vibration of two rotating blades
Applied and Computational Mechanics, 2013 This paper is aimed at modelling of friction effects in blade shrouding which are realized by means of friction elements placed between blades. In order to develop a methodology of modelling, two blades with one friction element in between are considered

Weight Effects on Vertical Transverse Vibration of a Beam with a Nonlinear Energy Sink
Applied SciencesReductions in the vibration of a continuum system via a nonlinear energy sink have been widely investigated. It is usually assumed that weight effects can be ignored if the vibration is measured from the static equilibrium configuration.
