| Abstract: | In China,many cities have adopted linear induction motor(LIM) rail transit system,but a specialized code of urban railway transportation has not yet been established. In this paper,the dynamic factor formulations of railway bridge in the world are introduced.Taking a typical bridge in Guangzhou metro Line 4 as the engineering background, this paper conducts the theoretical and experimental analyses for vehicle-bridge coupling vibration,and obtains the theoretical and experimental values of dynamic factors b... |
