โœฆ Synopsis

Non-linear normal modes and the associated frequencies of a uniform beam with simply-supported or clamped conditions at both ends have been derived. Some restricted orthogonality conditions have been pointed out. The effects of the longitudinal inertia on the non-linear transverse motion are shown to be extremely small. The efficacy of using the non-linear normal modes towards computation of near-resonance response has been clearly brought out.

In this paper, two factors that a!ect the behaviors of the non-linear normal modes (NNMs) of conservative vibratory systems are investigated. The "rst factor is the base points (which are equivalent to Taylor series expanding points) of the non-linear normal modes and the second one is the normaliza

The non-similar normal modes of free oscillations of a coupled non-linear oscillator are examined. So far, the study of non-linear vibrations has been based on the assumption that the system is admissible. This requirement is satis"ed when the sti!ness of the springs are odd functions of their displ

The relation between the wave propagation and the free vibration in a travelling beam with simple supports has been thoroughly investigated. The frequency equation of such a beam has been derived using the phase-closure principle. Since the characters of the waves change drastically as the axial spe

The wave propagation in a simply supported travelling beam, studied in Part I of this paper, has been used to derive the forced responses. Based upon the wave-propagation principles, a simple method for constructing the closed-form transfer function of such a beam has been presented. The use of this
