内容简介

　　《绳索驰振到混沌（英文版）》通过两自由度非线性振子、并基于有限傅里叶级数的解析方法，首次给出了流体诱导绳索驰振的解析解。此有限傅里叶级数法提供了非线性系统从时域到频域的非线性变换，从而应用频幅特征来确定非线性系统的动力学行为。根据其解析解，展示驰振绳索的周期运动到混沌的解析分岔道路。
　　《绳索驰振到混沌（英文版）》提供了解决工程中流体诱导振动的解决方法，可帮助人们更好地理解例如飞机、桥梁、高层建筑、换热器管道、高压电缆线中的流体诱导振动。

前言/序言

　　This book is about analytical galloping dynamics of nonlinear cables under fiow-induced dynamical loading. The galloping dynamics of cable under such fiuid dynamical loading is the fiow-induced structural vibration， which has been studied since the early nineteenth century. Flow-induced structural vibrations extensively exist in engineering， such as aircraft， bridge， power transmission lines， high structures and buildings. When a steady flow comes to an asymmetric slender elastic structure， the asymmetric flow vortex formed around such a structure will cause its structural vibration. To understand the mechanisms of such a phenomenon， different mathematical models and techniques have been developed. However， due to the nonlinearity of fluid forces relative to the orientation and velocity of the structure， in addition to experimental observation， one has developed linear modeling of structures with nonlinear fluid dynamical forces， and the perturbation method was employed to determine the inherent dynamical characteristics. In fact， the results are far behind experimental observed results. Without significant analytical results， one has a difficulty to determine the dynamic characteristics of fiow-induced structural vibrations. In this book， the galloping instability to chaos of nonlinea/r cables is considered as an example to show how to determine the analytical solutions of periodic motions in fluid-induced structural vibrations and further to find the frequency-amplitude characteristics which can be hired to control fiuid-induced structural vibrations.
