摘要：The car-bridge pavement roughness level has a great influence on the vibration of the coupled system and on the driving comfort. Numerical simulation model of vehicle-bridge coupling vibration analysis is established to study the vehicle-bridge system while vehicle running on a long-span bridge. The vibration characteristics of vehicle-bridge system and the driving comfort of vehicle are studied while vehicle running on a long-span bridge under different pavement roughness level. The results show that, the vertical impact coefficient and the comfort evaluation index both gradually increase with the improving level of roughness.
