Anharmonic Resonance Available to Purchase

The oscillations of a pair of classical oscillators which are synchronized because of anharmonic resonance can be calculated by the method of variation of constants. Two types of motion are studied: librational and nonlibrational—referring to oscillatory and progressive behavior, respectively, of the phase difference of the two oscillators. These motions are exemplified by the corresponding motion of a rod pendulum. Conditions for prolonged persistence of librational motion are discussed. This paper is essentially a review of some of E. W. Brown's papers on nonlinear resonance.
