Dynamic Response of Guideway with Running High-speed Maglev Train
High speed maglev is one of the most important reformations in the ground transportation systems because of its no physical contact nature. This paper intends to study the dynamic response of the single-span guideway induced by moving maglev train. The dynamic model of the maglev train-guideway system is established. In this model, a maglev train consists of three vehicles and each vehicle is regarded as a multibody system with 34 degrees-oMreedom. The guideway is modeled as a simply supported beam, an iterative approach is presented to compute the dynamic response of a maglev train-guideway system, he resonant conditions of single-span guideway are analyzed. The results show that all the dynamic indexes of train -guideway system are far less than permissive values of railway and maglev system ,the vertical resonant of guideways caused by periodical excitations of the train will not happen.
