Vibration analysis of maglev three-span continuous guideway considering control system

Abstract：The dynamic interaction between maglev vehicle and three-span continuous guideway is discussed. With the consideration of control system, the dynamic interaction model has been developed. Numerical simulation has been performed to study dynamic characteristics of the guideway. The results show that bending rigidity, vehicle speed, span ratio and primary frequency all have important influences on the dynamic characteristics of the guideway and there is no distinct trend towards resonance vibration whenf1/(v/l) equals 1.0. The definite way is to control impact coefficient and acceleration of the guideway.The conclusions can serve the design of high-speed maglev three-span continuous guideway. 作者： Author： Yan-feng TENG  Nian-guan TENG  Xin-jian KOU 作者單位： School of Naval Ocean, Architecture and Civil Engineering, Shanghai Jiao Tong University, Shanghai 200240, China 期 刊： 浙江大學學報A（英文版）   ISTICEISCI Journal： JOURNAL OF ZHEJIANG UNIVERSITY SCIENCE A 年，卷(期)： 2008, 9(1) 分類號： U441+.4 Keywords： Maglev transportation system    Three-span continuous guideway    Coupling dynamics    Feedback control    Numerical simulation    機標分類號： P7 O32 機標關鍵詞： dynamic characteristics    dynamic interaction    bending rigidity    control system 基金項目： 國家高技術研究發(fā)展計劃(863計劃)，國家高技術研究發(fā)展計劃(863計劃)
