| Abstract: | In this paper,a finite element analysis model for space vibration of the vehicle and the self-anchored suspension bridge is presented on the basis of normal modes by ANSYS.By taking three-dimensional coupling vibration of vehicle-bridge system in the Pingsheng Bridge as the research object,the vehicle-bridge space vibration response and impact factor are calculated by using self-developed program when the vehicles run through the bridge at different number of vehicles,vehicle spacing,road condition and vehicle speed.The results provide a reference for design of self-anchored suspension bridge. |
