Convergence improvements of the harmonic balance method
1993 IEEE International Symposium on Circuits and Systems, 2002Harmonic balance based circuit simulators, which allow an efficient evaluation of the steady state solution in the frequency domain, still present convergence failures in nonlinear circuit analysis. Such problems are investigated, giving emphasis both to the numerical aspects and to the theoretical bases of the method.

Harmonically forced Cavendish balance
American Journal of Physics, 1983The Cavendish balance, when driven into resonance by swinging the external mass, provides an interesting corridor demonstration of gravity. It is, moreover, a suitable means of demonstrating properties of driven harmonic systems.

The Method of Harmonic Balance
2011This method may be used to determine the approximate periodic solutions of nonlinear differential equations. If a periodic solution does exist, it may be sought in the form of a Fourier series, whose coefficients are determined by requiring the series to satisfy the equation of motion.

Oldham-Coupling Second-Harmonic Balancer
Journal of Mechanisms, Transmissions, and Automation in Design, 1984This paper describes a mechanical balancer, based on the Oldham-type shaft coupling, for reducing or eliminating second-harmonic out-of-balance in mechanical systems. It is shown that by proper arrangement of two Oldham couplings, a balancer can be obtained for the elimination of second-harmonic shaking forces or second-harmonic shaking moments or a ...

Harmonic balance analysis of a microwave balanced power amplifier
Canadian Conference on Electrical and Computer Engineering 2001. Conference Proceedings (Cat. No.01TH8555), 2002The purpose of this paper is to apply the harmonic balance (HB) method to a balanced microwave power amplifier. Also it shows a slight modification in the HB method, which can be applied on many practical microwave circuits. The analysis is accurate, and the modification results in less execution time.

Solving the Harmonic Balance Equations
2019Harmonic Balance leaves us with a problem to be solved: a nonlinear algebraic equation system with respect to the Fourier coefficients of the approximation. In this chapter, we categorize the fundamentally different strategies suited for solving such equation systems. We then focus on local numerical methods, in particular on Newton-type methods. These

New applications of harmonic balance analysis
International Journal of Microwave and Millimeter-Wave Computer-Aided Engineering, 1995AbstractThis article shows how the theory of averaging extends applications of harmonic balance analysis. Two examples are given: (i) a new approach to high‐Q oscillators, which results in an analysis of slowly varying envelope of oscillations rather than the oscillations themselves; and (ii) a rigorous analysis of frequency lock and of stability of ...

Complete Balancing of Multicylinder Engines Without Requiring Harmonic Balancers
Volume 3C: 15th Biennial Conference on Mechanical Vibration and Noise — Vibration Control, Analysis, and Identification, 1995Abstract Presently used balancing methods for multicylinder engines and pumps are for partial balancing. As a result the complete shaking force, shaking torque, and shaking moment balancings of engines require the use of harmonic force and harmonic torque and moment balancers. This article presents a new method for complete shaking force

Harmonic balance and the Hopf bifurcation
Mathematical Proceedings of the Cambridge Philosophical Society, 1977SummaryA form of the Hopf bifurcation theorem specially suited to systems in block-diagram form has been developed, which allows one to deal with high or infinite order linear elements solely in terms of their transfer functions. The results are proved by the method of harmonic balance, and, for general non-linear systems, lead to criteria for the ...
