Chapter 1: Introduction to Harmonic Balance Method (HBM) Analysis

The Harmonic Balance Method (HBM) is useful for solving structural dynamics forced response problems with local nonlinearities. Some examples of physical systems that can be modeled with HBM include:

  • Under-platform dampers of a jet engine bladed disk

  • Bolted joints in a flange assembly

  • A beam with a small crack

The HBM general equations are presented first, followed by specifics for HBM cyclic equations.
