Harmonic Synthesis Theory for Dynamic Spring Balancing

Journal of Dynamic Systems, Measurement, and Control, 1997
At resonance, a small excitation force amplitude results in a relatively large amplitude system response. Although typically viewed as undesirable, operating a machine near resonance can sometimes be advantageous. A new approach to dynamic spring balancing, called harmonic synthesis, tunes a system so that the desired dynamic motion is approximated by ...

Harmonized Profiloplasty Using Balanced Angular Profile Analysis

Aesthetic Plastic Surgery, 2004
To evaluate outcomes of aesthetic facial plastic surgery objectively the authors developed a photogrammetric profile analysis method, which they call "balanced angular profile analysis" (BAPA). To develop standards and ways to determine the conformation of various soft tissue segments analytically, 19 mean angular values acquired from the photographs ...

Harmonic Balance Finite Element Method

2016
The art of HBFEM is to use Computational Electromagnetics (CEMs) with harmonic balance theories, and CEM technologies (with IEEE Standard I597.1 and IEEE Standard 1597.2) to analyze or investigate nonlinear EM field and harmonic problems in electrical and electronic engineering and electrical power systems.

Convergence improvements of the harmonic balance method

1993 IEEE International Symposium on Circuits and Systems, 2002
Harmonic 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, 1983
The 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

2011
This 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, 1984
This 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), 2002
The 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

2019
Harmonic 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
