On a new harmonic selection technique for harmonic balance method [PDF]

open access: yesMechanical Systems and Signal Processing, 2012
This paper is intended to present a new harmonic selection technique when solving nonlinear dynamic systems with the harmonic balance method. This technique belongs to the class of method called the adaptive harmonic balance method (AHBM). The harmonic selection is based on the use of a tangent predictor and relies on a stepwise regression procedure ...
