| Abstract: | A vehicle-guideway-pier dynamic model of high-speed maglev system was established based on bridge dynamics,car dynamics and electromagnetic interaction between vehicle and guideway girder.The large nonlinear coupling dynamic equations were solved by numerical integration.Vehicle-guideway dynamic checking computations under concrete line conditions were done and some basic laws of dynamic response of vehicle-guideway-pier system moving on curves were gained.The study lays down a theoretical foundation for line design criterions in high-speed maglev system. |
