Abstract: To study effects of parameters of a vehicle-bridge system on dynamic magnification factor, a simply sup-ported bridge is modeled an Euler beam with equal length, and a moving vehicle is modeled a two-degree-of-freedom system with five parameters. The dynamic responses of the combined system can be obtained by solving the vehicle-bridge coupled vibration equations. The dynamic magnification factor for displacement and bending moment are defined. Effects of road-surface roughness, bridge damage, vehicle parameters and vehicle speed on the impact are studied with numerical simulations.
