Comments on the Method of Harmonic Balance for Nonlinear Conservative Single-Degree-of-Freedom Systems
Although the method of harmonic balance is well-known to analyse approximately nonlinear vibrations, its application includes always a certain risk if it results in good approximations or if it fails. In this contribution some facts on this method are summarized. Together with the experience of many academic and practical examples some comments are presented resulting in recommendations when the method of harmonic balance may be or may be not applied.
