Multi-level residue harmonic balance method for nonlinear vibration of the beam

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2022
This study presents the nonlinear vibration and chaotic response of a beam subjected to harmonic excitation. The multi-level residue harmonic balance method is applied to solve the geometrically cubic nonlinear vibration of the simply supported beam. The

A Mixed Shooting – Harmonic Balance Method for Unilaterally Constrained Mechanical Systems

open access: yesArchive of Mechanical Engineering, 2016
In this paper we present a mixed shooting – harmonic balance method for large linear mechanical systems on which local nonlinearities are imposed. The standard harmonic balance method (HBM), which approximates the periodic solution in frequency domain ...

Prediction of Transient Pressure Fluctuations within a Low-Pressure Turbine Cascade Using a Lanczos-Filtered Harmonic Balance Method

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2021
Unsteady pressure fluctuations measured by fast-response pressure transducers mounted in a low-pressure turbine cascade are compared to unsteady simulation results. Three differing simulation approaches are considered, one time-integration method and two

A frequency-domain approach to the analysis of stability and bifurcations in nonlinear systems described by differential-algebraic equations

open access: yes, 2007
A general numerical technique is proposed for the assessment of the stability of periodic solutions and the determination of bifurcations for limit cycles in autonomous nonlinear systems represented by ordinary differential equations in the differential ...

The Elliptic Harmonic Balance Method for the Performance Analysis of a Two-Stage Vibration Isolation System with Geometric Nonlinearity

open access: yesShock and Vibration, 2021
This study develops a modified elliptic harmonic balance method (EHBM) and uses it to solve the force and displacement transmissibility of a two-stage geometrically nonlinear vibration isolation system.

Frequency-Domain Analysis of Linear Time-Periodic Systems [PDF]

open access: yes, 2004
In this paper, we study convergence of truncated representations of the frequency-response operator of a linear time-periodic system. The frequency-response operator is frequently called the harmonic transfer function. We introduce the concepts of input,

Examination of sub-harmonic responses along with various initial conditions induced by multi-staged clutch damper system

open access: yesScientific Reports, 2022
Using the harmonic balance method to investigate the nonlinear dynamic behaviors pertaining to sub-harmonic responses is difficult compared with that of super-harmonic cases because of the limitations of the HBM.
