| Abstract: | Maglev transportation has been paid more attention recently in China since it has many advantages, such as wide speed range, smaller turning radius, and higher climbing ability. Similar with the traditional wheel/rail train, strong interaction vibration problems of the maglev vehicle-suspension-guideway system also occur in the commercial operation lines, which may lead to safety and stability problems of the maglev train. Therefore, it has practical significance to study the dynamic interaction mechanism of maglev vehicle-suspension-guideway system by both numerical and experimental method. To analyze the dynamic interaction mechanism of maglev vehicle-suspension-guideway system, three train models including a moving load model, moving mass model, and multiple moving mass model are established for the maglev train. The solutions for the three train models moving on a simply supported beam are derived. In addition, the in-suit testing is implemented in a low-medium maglev test line and the testing data are used for verifying the accuracy of the established maglev train model. Furthermore, the dynamic features of the low-medium maglev vehicle-suspension-guideway system are also analyzed by using the testing data. Finally, the malfunction detection of the suspension controller by using wavelet method is presented in this dissertation. |
