Abstract

By Poincare surface of sections, dynamical features of manifold in two, three or high dimensions can be investigated. Characteristics of Poincare sections for all kinds of manifold can be obtained qualitatively, which is used to study system with high dimensions by reducing dimension. In present work, a method of quick detection on occurrence of vortex-induced vibrations (VIV) of cylindrical structure is developed from measured time history of one variable by using Poincare surface of section. Experimental results have shown that such method is quick and reliable as a new means of engineering detection on VIV of cylindrical structure.
