內容簡介

　　《繩索馳振到混沌（英文版）》通過兩自由度非綫性振子、並基於有限傅裏葉級數的解析方法，首次給齣瞭流體誘導繩索馳振的解析解。此有限傅裏葉級數法提供瞭非綫性係統從時域到頻域的非綫性變換，從而應用頻幅特徵來確定非綫性係統的動力學行為。根據其解析解，展示馳振繩索的周期運動到混沌的解析分岔道路。
　　《繩索馳振到混沌（英文版）》提供瞭解決工程中流體誘導振動的解決方法，可幫助人們更好地理解例如飛機、橋梁、高層建築、換熱器管道、高壓電纜綫中的流體誘導振動。

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.
