摘要
The dynamic interaction between moving vehicles and two-span continuous guideway was discussed. With the consideration of the magnetic levitation system,the maglev vehicle/guideway dynamic interaction model was developed.Numerical simulation was performed to understand dynamic characteristics of the guide- way used in practice.The results show that vehicle speed,span length and primary frequency of the guideway have an important influence on the dynamic responses of the guideway and there is no distinct trend towards resonance vibration when f_1 equals 1.0.The definite way is to control the impact coefficient and acceleration of the guideway.The conclusions can serve the design of high speed maglev guideway.
