| Abstract: | Based on vehicle-track coupling dynamics and dynamic finite element, a dynamic model was developed to investigate the vertical interaction between maglev train and guideway.The dynamic responses were calculated by means of a computer program, and the random responses power spectrums of the vehicle and the guideway show that the analytic theory and the methods here presented are valid. The present work has laid the foundation for further study of the mechanical properties of maglev system and improvement of design methodology and maintenance ofmaglev. |
