Forced Vibration in an Unsymmetric Piecewise-linear System Excited by General Periodic Force with Arbitrary Function

摘要

This paper discusses forced vibration in an unsymmetric piecewise-linear system without damping excited by general periodic force with an arbitrary function. The main resonance are analyzed by mean of a perfect Fourier series method. In numerical calculation, the exciting force are assumed to be odd function with the second higher harmonics only as an example. The theoretical resonance curves are calculated by a digital computer and are compared with the results obtained by an analog simulation. They show a fairly good agreement.
