Convergence of Volterra series applied to analysis of nonlinear dynamic circuits

Физика волновых процессов и радиотехнические системы, 2014
The behavior of the Volterra model for nonlinear dynamic circuits is explored. It is shown that the critical signal levels for the convergence of the Volterra series - these are the points of explicit or implicit transition of nonlinear model from one ...

On Large Amplitude Vibrations of the Softening Duffing Oscillator at Low Excitation Frequencies—Some Fundamental Considerations

Applied Sciences
The Duffing equation containing a cubic nonlinearity is probably the most popular example of a nonlinear oscillator. For its harmonically excited, slightly damped, and softening version, stationary large amplitude solutions at subcritical excitation ...

Improving accurate vibration periods and responses of a rigid rod model

Alexandria Engineering Journal, 2018
In this paper, we construct a residue harmonic balance solution procedure to improve the accuracy of approximate vibration period and steady response for a strongly nonlinear oscillator from the motion of rigid rod rocking back and forth on a circular ...

A Multi‐Scale Machine Learning Framework for the Inverse Design of High Entropy Alloys

Advanced Engineering Materials, EarlyView.
High‐entropy alloys offer vast potential for various applications, including electrocatalysis; however, their compositional complexity challenges conventional screening. We introduce an inverse‐design framework combining two neural networks to determine optimal compositions and reconstruct nanoparticle geometry from targeted properties and conventional

A Semidefinite Programming Approach for Harmonic Balance Method

IEEE Access, 2019
The harmonic balance method is broadly employed for analyzing and predicting the periodic steady-state solution. Most of the traditional methods in the literature do not guarantee global optimality. Due to its nonconvexity, it is a complex task to find a

Comments on the method of harmonic balance [PDF]

Journal of Sound and Vibration, 1984
Scientists and engineers are often confronted with a non-linear ordinary differential equation for which physical considerations suggest that one or more types of oscillatory motions are possible. In general, except under very special conditions, exact solutions in closed form do not exist.
